Joint Source-Channel Coding Over a Fading Multiple Access Channel with Partial Channel State Information

Free registration required

Executive Summary

In this paper, the authors address the problem of transmission of correlated sources over a fast fading Multiple Access Channel (MAC) with partial channel state information available at both the encoders and the decoder. They provide sufficient conditions for transmission with given distortions. Next these conditions are specialized to a Gaussian MAC (GMAC). They provide the optimal power allocation strategy and compare the strategy with various levels of channel state information.
