Rate-Optimal Video Transmission Over MIMO Channels

Free registration required

Executive Summary

In this paper, the authors propose a low complexity method for optimal video transmission over a quasi-static Rayleigh fading channel utilizing multiple transmit and receive antennas. Under the assumption that the total transmission bandwidth is fixed, their method jointly selects the optimal Space-Time Code (STC) with fixed and finite signal alphabet and the optimal Reed-Solomon (RS) channel code rate with fixed codeword length to protect a video bitstream against channel bit errors. The numerical results of their scheme in comparison with alternative schemes, reveal its performance advantage over other schemes for different video sequences.
