<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.
