摘　　要：通信系统的优化可用最优编码方式实现,不同的系统优化指标可产生不同的最佳编、译码方式.从通信系统的优化理论入手,论证了用信源信道联合编码(joint source-channel coding, JSCC),实现通信系统整体优化的可行性,并给出了一个基于信源信道统计特性的联合编译码实例及其结果分析.实验结果表明:采用该方案使译码效率和传输性能都得到了改善.Using the optimum code can obtain the optimization of communication system. Different system optimization targets can produce different optimum code. In this paper, starting with the theory of communication system optimization, the feasibility of communication system optimization with joint source-channel coding(JSCC) is demonstrated, an example for joint source-channel coding with its application analysis is given. The experience results show that the scheme will improve the decoding effieciency and transmission performance.
