    <p>In order to meet the current transmission and QoS demands of wireless video transmission, the conventional wireless systems are using Multiple Input Multiple Output (MIMO) technology aided with receiver channel state information (CSI) feedback. The CSI is used by the access point to accurately measure the users' channel quality to decide the best transmission and video encoding parameters possible for each user. However, the CSI feedback has some disadvantages such as the delayed reception at the transmitter, the CSI expiry due to the doppler shift, and finally, hardware complexity making it difficult to be implemented in low power and low cost devices. In this paper, we propose the transmission of H.264/SVC video bitstreams through MIMO system by using the received signal strength indicator (RSSI) instead of CSI. To supplement the RSSI, we implement a look-up table based mechanism to predict the video PSNR for any wireless propagation environment. Aside from being widely supported in all wireless devices, the RSSI can be obtained from the clear to send (CTS) packets in without the need of a sounding process. The results show that our proposed method improves the PSNR by more than 16 dB, and has 6 meters more range compared with the conventional method with fixed encoding ratio and packetization.</p>

    In this paper, we propose a hardware development of a high accuracy Precision Time Protocol (PTP) on Software Defined Radio (SDR) for Industrial WLAN systems. To increase the throughput of the transmission system, we propose a low overhead 3-frames exchange PTP instead of 4-frames transmission as IEEE 1588 PTP protocol. Besides, our hardware-software co-design of the full SoC MAC-PHY can select the PTP timestamp point to remove the random transmission jitters caused by higher layers and the imbalanced timing made by the rugged hardware designs between master and slave. In previous work, the PTP synchronization has been evaluated on the M820-ZYNQ platform with Dummy PHY. In this paper, the proposed PTP system is developed on the SDR platform with real PHY. The SDR platform can reduce the processing delay between software and hardware compared to the previous platform. The result of our demonstration experiments shows that an oscilloscope captures the time synchronization of the proposed system in high accuracy with the nano-second level, which is less than 200 ns.

    <p>Mobile video traffic is expected to increase explosively because of the proliferating number of Wi-Fi terminals. An overloaded multiple-input multiple-output (MIMO) technique allows the receiver to implement smaller number of antennas than the transmitter in exchange for degradation in video quality and a large amount of computational complexity for postcoding at the receiver side. This paper proposes a novel linear precoder for high-quality video streaming in overloaded multiuser MIMO systems, which protects visually significant portions of a video stream. A low complexity postcoder is also proposed, which detects some of data symbols by linear detection and the others by a prevoting vector cancellation (PVC) approach. It is shown from simulation results that the combination use of the proposed precoder and postcoder achieves higher-quality video streaming to multiple users in a wider range of signal-to-noise ratio (SNR) than a conventional unequal error protection scheme. The proposed precoder attains 40dB in peak signal-to-noise ratio even in poor channel conditions such as the SNR of 12dB. In addition, due to the stepwise acquisition of data symbols by means of linear detection and PVC, the proposed postcoder reduces the number of complex additions by 76% and that of multiplications by 64% compared to the conventional PVC.</p>

    © 2018 IEEE. Wireless video transmission over multiple-input multiple-output (MIMO) systems is a challenging theme. Eigen beam-space division multiplexing (E-SDM) is an optimal beamforming technique in terms of channel capacity when the transmitter and receiver can share channel state information. E-SDM sorts the channel quality from the highest signal-To-noise ratio (SNR) to the lowest one. This paper presents the video transmission scheme for H.264 scalable video streams over MIMO E-SDM with optimized packetization. The proposed method controls the ratio of a base layer and enhancement layers contained in a packet. The result shows that the optimized ratio is obtained when a packet consists of the lowest base layer ratio. This ratio provides the 39.9 dB of peak-signal-To-noise ratio after decoding while no frame can be decoded with the other ratio at SNR of 10 dB.

    © 2018 IEEE. In this paper, a new architecture of a multi-mode Fast Fourier Transform hardware for IEEE 802.11ax WLAN standard is presented. The proposed architecture is based on Radix-2 Multipath Delay Commutator (MDC), Radix-2 2 and Radix 2 4 Single-path Delay Feedback(SDF) stages. To optimize the throughput and area of the FFT hardware, we applied two design techniques such as compression of redundant twiddle factors, and optimization of twiddle factor multiplication. In FPGA implementation using Altera Stratix IV EP4SGX530KH40C3, the proposed FFT achieved 1.2 GSamples/s throughput and met the requirements of the 802.11ax standard. The synthesis results show that the proposed circuit is 6.19% lower latency and 30.2% lower area compared to a recently presented work while maintaining higher working frequency.

    © 2018 IEEE. High efficiency video coding (HEVC) is the newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The introduction of multiple-input multiple-output (MIMO) eigenbeam-space division multiplexing (E-SDM) systems makes it possible to increase data rate by multiplexing different data streams on multiple parallel eigen-channels. In this paper, we propose a MIMO video transmission scheme for scalable high efficiency video coding (SHVC), which is the scalable extension of H.265/HEVC. Simulation results show that our video transmission scheme has more potential to broadcast video streams efficiently than conventional MIMO systems.

    <p>High-resolution image and video communication in home networks is highly expected to proliferate with the spread of Wi-Fi devices and the introduction of multiple-input multiple-output (MIMO) systems. This paper proposes a joint transmission and coding scheme for broadcasting high-resolution video streams over multiuser MIMO systems with an eigenbeam-space division multiplexing (E-SDM) technique. Scalable video coding makes it possible to produce the code stream comprised of multiple layers having unequal contribution to image quality. The proposed scheme jointly assigns the data of scalable code streams to subcarriers and spatial streams based on their signal-to-noise ratio (SNR) values in order to transmit visually important data with high reliability. Simulation results show that the proposed scheme surpasses the conventional unequal power allocation (UPA) approach in terms of both peak signal-to-noise ratio (PSNR) of received images and correct decoding probability. PSNR performance of the proposed scheme exceeds 35dB with the probability of over 95% when received SNR is higher than 6dB. The improvement in average PSNR by the proposed scheme compared to the conventional UPA comes up to approx. 20dB at received SNR of 6dB. Furthermore, correct decoding probability reaches 95% when received SNR is greater than 4dB.</p>

    高解像度な動画像無線伝送技術の需要が世界的に高まっており,効率的な動画像伝送の手法について多くの研究がなされている.本稿では情報源符号化と通信路符号化を組み合わせて復号画像の画質劣化を抑制するJSCC(joint source-channel coding)手法に基づく動画像伝送システムのハードウェア実装について提案する.提案法は画質への寄与度の高いレイヤをE-SDM(eigenbeam-space division multiplexing)により通信路容量の大きい通信路で伝送することで,最低画質を保証しつつ高画質化を図っている.ハードウェアモデルを組み込んだシミュレーションより,E-SDMを施さない従来システムでは動画像伝送が困難な低SNR時でも提案法は高画質な動画像伝送が可能であることを示す.

    近年,次世代無線LAN 規格のひとつとして,IEEE802.11bf ワーキンググループにおけるチャネル状態情報(CSI:Channel State Information) を活用したセンシング技術の研究開発が関心を集めている.無線LANは最も普及している無線通信インフラの一つであることから,CSIセンシングはスマートホームやヘルスケア分野などへ経済的かつ容易に応用できると期待されている.無線LANを用いたセンシング技術の研究では,学習の際に大量のラベル付きデータが必要となる「教師あり学習」が多く採用されているが,センシングのシステムを適用する環境ごとに学習に必要な量のラベル付きのCSIデータを収集することは困難である.そこで,本稿ではデータへのラベル付け作業にかかるコストを軽減する手法として,「半教師あり学習」の手法の一つである自己訓練モデルを用いた,少量のデータに対してのみラベル付けを行い,大量のラベルなしデータと組み合わせて学習を行う手法を提案し,室内環境におけるCSIデータの分類問題に適用する.提案手法を適用したところ,半教師あり学習を用いた自動ラベリングを行うことによって,CSIセンシングにおいて人間の有無(位置)の分類を90%以上の確率で達成したことを報告する.

    近年,Factory Automation(FA)の分野では通信エラーを生じさせない無線化システムが望まれている.
    本研究では,無線LAN規格IEEE 802.11をベースとした高信頼な産業用無線LANシステムを実現する.
    本システムは,特に,システムの信頼性を保証するため,データ誤りが生じた際の再送処理の手法や,
    PDMAおよびFDMA伝送方式による複数台の端末との同時通信の対応など,
    ネットワークの下位レイヤであるMAC層とPHY層における独自の仕様を実装している.
    一方,高信頼性を保証するためには,通信エラー率の検証に長期の時間を要するため,その定式化が重要である.
    本研究では,実環境を想定して,3年単位で安定して稼働するシステムであることを,通信エラー率の定式化より定量的に評価を行う手法を検討し,信頼性の評価を行う.
    今回の評価では,システムの通信において,少なくとも1回のシステム再送と,無線LAN部における2回の再送回数を行うと,
    3年間の運用を行った際にも信頼性を保証できることを確認した.よって,定式化よりエラー率を求めることで評価を行うことができた.

    近年,スマートフォンを代表とする無線LANに対応する端末が急速に増加している.それに伴う無線LANアクセスポインタなどの増加により,エリア内で同一チャネル上で通信を行うOverlapping Basic Service Set (OBSS)の影響が顕著になっている.このような稠密環境では無線LAN内のMACスループットが
    大幅に低下する.IEEE802.11ax無線LAN規格では高効率を目標に,周波数資源を複数端末に割りあてて複数端末の同時通信を行うマルチユーザ伝送が規格化された.また,マルチユーザ伝送の成功率を高める機能として従来Request to Send/Clear to Send(RTS/CTS)メカニズムを機能拡張したMulti User RTS/CTS (MU-RTS/CTS)を規格化したが,稠密環境では従来の隠れ端末問題・さらし端末問題などが複雑化するため,MU-RTS/CTSによるMACスループット向上の効果は明らかになっていない.
    本報告では,コンピュータシミュレーションにより稠密環境を再現し複数
    Modulation and Coding Scheme (MCS)においてMU-RTS/CTSを使用した場合と使用しない場合を比較してMU-RTS/CTSのMACスループット向上への有用性を示す.シミュレーションを行なった稠密環境においてDownlink (DL)にMU-RTS/CTSを用いることで各MCSにおいてBSS全体のMACスループットが45%以上増加したことを確認した.

    IEEE802.11be では,1 台の端末が複数の周波数帯を並列集約運用するマルチリンクオペレーションが検 討されている.限られた周波数資源を効率的に利用するためには,稠密環境において干渉を回避するチャネルアク セス手法が必要となる.しかし,マルチリンクオペレーションは現在規格化段階の技術のため,稠密環境における 干渉回避に関するチャネルアクセスについて十分な検証が行われていない.チャネルアクセスにおける重要なパラ メータとして,送信電力や伝送レートなどがあるが,その中でもキャリアセンス感度は干渉の回避に関係するとと もに送信機会にも影響を与える.本報告では,稠密環境における マルチリンクオペレーションのスループット向上 のため,マルチリンクオペレーションとキャリアセンス感度の関係について検証する.

    Recently, with the tremendous diffuser of smartphones, the SNS users rate has increased to 74.7 %
    in 2018. Users can easily send and receive the various images via the Internet such as SNS. In addition, image
    processing technology has been developed, making it possible to easily process images. On the other hand, with
    the development of image processing technology, images are often tampered by malicious users to be different from
    the facts and spread on SNS, which is a social problem. Digital watermark, which is a method to solve such the problems, has attracted attention. This method embeds a digital watermark directly in the image, and the receiver side extracts the digital watermark from the tampered image, which is used as a method of tamper detection and recovery of the tampered image. However, this method does not support the image format JPEG (Joint Photographic Experts Group) often used in SNS, and converting an image which is embedded digital watermark to JPEG breaks the digital watermark and does not work well. In this report, we propose the method of tampering detection and self-recovery by using robust digital watermark against JPEG compression, and evaluate its performance by software simulation.

    Highly accurate timestamps of device's local time is required in IoT sensor networks.
    This is because the timestamp information is important for measured data analysis.
    However, the conventional high-precision time synchronization method generally requires special hardware and hence difficult to implement in small IoT devices.
    In this paper, we present a high-accuracy clock offset estimation method that achieves a maximum error of 50 ns by software processing using only ToA(Time of Arrival) information obtained by each node in a wireless LAN network.

    In this paper, we propose a system that verifies and corrects the accuracy of symbol timing synchronization processing to determine reception time in Wi-Fi system.
    Time-of-flight (ToF) -based Wi-Fi indoor mobile position estimation uses radio time-of-flight data between the mobile terminal targeted for position estimation and a fixed Wi-Fi receiver (anchor) Using. However, it is known that the accuracy of radio reception time data in existing Wi-Fi receivers may be deteriorated due to the influence of multipath environment.
    Therefore, we consider a system that corrects the accuracy of symbol timing synchronization processing that determines the reception time of radio waves in the Wi-Fi system. This will improve the estimation accuracy of Wi-Fi indoor mobile position estimation.

    <p>Recently, aerial Mars exploration systems have been actively researched. Because the atmospheric density of Mars is almost one-hundredth to that of Earth's, the flight Reynolds number becomes low (Re = 10<sup>4</sup> ~ 10<sup>5</sup>). In low Reynolds numbers, the flow around a wing tends to separate and conventional airfoils cannot satisfy the given performance requirements for Mars exploration aircraft. In recent years, Sasaki et al. researched new airfoils that have high lift-to-drag ratio at low Reynolds number using evolutionary multi-objective optimization and computational fluid dynamics. In this research, two-dimensional wind tunnel test of three airfoils proposed by Sasaki et al. is conducted to investigate their actual aerodynamic characteristics at Reynolds number 2.0 &times; 10<sup>4</sup>. The Ishii airfoil with good performance at low Reynolds number is used as the benchmark. The result of the wind tunnel test showed that the lift curve of the three airfoils is linear, and their maximum lift coefficient and stall angle are larger than those of Ishii. Particularly, the three airfoils' lift-to-drag ratio is superior to the Ishii airfoil by more than 30%.</p>

    Interleave division multiple access (IDMA) is a Non-Orthogonal Multiple Access (NOMA) technique regarded as an enabling technology for next generation wireless systems. IDMA can improve the system efficiency by supporting multiple access for a large number of stations. In this paper, we employ higher order QAM modulation up to 256-QAM for high spectral efficiency transmission. We show our receiver architecture which uses a soft demapper that significantly decreases the receiver detection complexity. Our proposed system is much more suited in modern multi-mode transceivers aside from the fact that it has a lower complexity.
