Abstract: A wireless video transmission architecture relying on the emerging LS-MIMO technique is proposed. Upon using the most advanced high efficiency video coding (also known as H.265), we demonstrate that the proposed architecture invoking the low-complexity linear zero-forcing detector and dispensing with any channel coding is capable of significantly outperforming the conventional small-scale MIMO-based architecture, even if the latter employs the high-complexity optimal maximum likelihood detector and a rate- 1/3 recursive systematic convolutional channel codec. Specifically, compared to the conventional small-scale MIMO system, the effective system throughput of the proposed LS-MIMO-based scheme is increased by a factor of up to three, and the quality of reconstructed video quantified in terms of the PSNR is improved by about 22.5 dB at a channel SNR of E<sub>b/N0</sub> ~ 6 dB for delay-tolerant video file delivery applications, and about 20 dB for lip-synchronized real-time interactive video applications. Alternatively, viewing the attainable improvement from a power-saving perspective, a channel SNR gain as high as &#x03B4;<sub>Eb/N0</sub> ~ 5 dB is observed at a PSNR of 36 dB for the scenario of delay-tolerant video applications, and again, an even higher channel SNR gain is achieved in the real-time video application scenario. Therefore, we envisage that LS-MIMO-aided wireless multimedia communications is capable of dispensing with the power-thirsty channel codec altogether!
