Examples
- 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
本论文可以分成四部分：第一部分给出了信源编码的基本概念和理论分析，重点放在最优均匀量化编码的研究方面；第二部分给出了信道?信源联合编码的原理叙述，重点放在复合式信道?信源编码的分析研究上；第三部分将信道-信源联合编码原理应用在两种噪声信道上：离散无记忆信道和cdma信道，并根据两种信道的不同特点详细描述了两种相应的编码设计方案；第四部分给出了复合式信道-信源编码的仿真结果以及对结果的相应分析。
