Abstract :
This paper considers to minimize the overall input-output distortion for wireless systems with analog inputs through joint source-channel coding. Taking a mixed analog-digital perspective, the source-aware non-uniform data transmission schemes are proposed by exploiting the non-uniformity in both channel coding and modulation design. Effect of channel coding is discussed and extension to systems with space-time diversity is also presented. Simulation results are provided to illustrate the proposed approaches.
