摘要：

In this paper, we investigate the behavior of the optimum end-to-end distortion of transmission over a multiple-input multiple-output (MIMO) channel. Assuming that a white noise source is transmitted over a Rayleigh fading MIMO channel and joint source-channel coding is performed at the transmitter knowing the instantaneous channel rate, we derive the analytic expressions of optimum expected end-to-end distortion over the whole range of SNR for both uncorrelated channels and spatially correlated channels. On this basis, considering the case of asymptotically high SNR, we derive the asymptotical form of the optimum expected distortion, which is composed of the optimum distortion SNR exponent and the corresponding distortion factor. This provides a more detailed analysis of analog source transmission over a MIMO channel.Chen, Jinhui; Slock, Dirk T M
