Theoretical Analyse & Simulation Of Channel-Source Coding

Abstract: This paper is mainly about my research work on source quantization and source coding ?The basic method is to optimize the system coding by use of combining the channel coding and source coding or parts of these two coding , and there presented a new approach of source quantization, combined source-channel quantization ?This paper can put into four parts ?This first part is the description and theoretical analyses of source coding, which focus on the research of optimizing equal quantization ?The second part presents the theoretical description of joint channel-source coding, which focus on the research of combined channel-source coding o The third part is about the application of combined channel-source coding to two different channel models, binary symmetric channel and cdma channel o In this part, two different coding designs are given according to different characters of these two channels?And the last part is the description of simulation of combined channel-source coding ?Most of my work are about two parts, one is to find the most appropriate quantization steps and centroid points of separate channel-source coding, another is to simulate the combined channel-source coding ?Comparing the simulation results of separate channel-source coding and combined channel-source coding, the characters of joint channel-source coding are given ?...
