    <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>

    <p>The emerging applications in the 5th generation (5G) network, such as industrial control system and Machine-to-Machine (M2M) communication require high reliability and low latency communication at the same time. The retransmission scheme is one of the practical approaches to increase system reliability when other diversity techniques are avoided due to hardware complexity or significant transmission delay. In order to address such problems, in this paper, we propose a fast yet reliable retransmission scheme. The proposed retransmission scheme leverages the frequency diversity through simple channel selectivity. The channel selectivity is carried out by employing low complexity subcarrier allocation for selecting other channels in Orthogonal Frequency Division Multiplexing (OFDM) transmission. The evaluation results show that the proposed retransmission method outperforms the conventional scheme. The proposed method can reduce the number of retransmission by up to 30%, corresponding to a success rate of 0.9999 . In addition, it can be employed in an industrial Wireless Local Area Network (iWLAN) system with a large number of users. The achievable control duration is around 52-63 μs, an improvement of approximately 36% compared to the conventional system.</p>

    <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>

    <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>

    Uplink-Multi user transmission, a key technology in the upcoming next generation wireless LANs standard IEEE 802.11ax has adopted Orthogonal Frequency Division Multiple Access (OFDMA) random access. In this paper, we propose a performance analysis model which uses two-dimensional Markov chain model of OFDMA random access. We show that the proposed model can be represented as the extended model of Bianchi's model which is a typical analytical model of Distributed Coordination Function. The efficiency and throughput of OFDMA random access are analyzed by using the proposed analytical model. The analytical result shows a very close result to the simulation result in highly dense environment via computer simulation. In addition, we show that the efficiency of OFDMA random access is improved by using appropriate Medium Access Control (MAC) parameter through analyzing efficiency by focusing each MAC parameter.

    <p>As complexity of system LSI design is increased significantly, efficient verification methodology is mandatory to achieve reliable system and to speed up development time. HW/SW co-verification, nowadays, is interesting and practical as a tool for system verification because it allows covering large number of verification scenarios in acceptable time. In this paper, we present an efficient and unified framework of HW/SW co-verification methodology for large scale system, particularly high throughput wireless communication system. The proposed methodology combine system level simulation (e.g., MATLAB or C/C++) and physical level verification (e.g., FPGA). It allows performing fast HW/SW verification, as well as fast turn-around design exploration. The proposed methodology has been successfully employed to our case study which is 4x4 MIMO wireless communication system. Experimental results show that our case study is able to run in near real-time processing, resulting in an improvement of simulation time orders of magnitude faster than software based simulation. Moreover, the proposed verification platform can be used for complete characterization of communication performance of a MIMO wireless system employing MLD MIMO decoder for various operation modes and channel models.</p>

    In this work, an industrial Wireless Local Area Network (iWLAN) system used to control industrial robots (iRBs) in factory automation (FA) environments is addressed. For fast and safe communications, we first propose a synchronous multi-user round-robin transmission protocol. To reduce the overhead caused by the conventional multi-user downlink transmission technique, we then propose a low overhead Packet Division Multiple Access (PDMA) transmission technique. The numerical and simulation results indicate that our approaches increase speed of 100% and 300% throughput compared to the conventional industrial Point Coordination Function (iPCF) and Space Division Multiple Access (SDMA) approaches, respectively. Besides, our approaches also provide lower system error rate (SER) than conventional ones. In particular, the control duration per iRB in our iWLAN system is faster than 100μsec. Therefore, our proposed schemes can achieve fast and safe performance for FA communication systems.

    Transmission rate control in wireless LANs is one of the factors that affect communication quality. Although many transmission rate control algorithms have been proposed, there are cases in which existing algorithms cannot adaptively control the rate depending on changes in the wireless communication environment. In this study, we propose a transmission rate control method using Deep Q-Network (DQN) to adapt to changes in the communication environment due to node movement. We evaluate the proposed DQN-based transmission rate control using the ns3-ai framework.

    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.

    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.
