Recently, there has been considerable interest in source transmission over wireless networks. There has also been some theoretical interest in evaluating source fidelity over a multi-hop channel, and in comparing source and channel diversity for various channel conditions. Compression and transmission of data signal have made the stringent demand on the quality of the reconstructed signal. Multipath fading can seriously degrade quantization system performances of wireless transmission. Therefore, upgrading transmission reliability and increasing channel capacity withhout icreasing transmission power and bandwith are the main problems. Optimizaton of quantization, coding and transmission techniquesis are the basic mission of modern digital signal processing in wireless communications [1, 2].
