摘　　要：介绍联合信源信道算术码添加禁用符号的编码方法,以实例方式引入联合信源信道算术码的检错原理。综述联合信源信道算术码的检错时延分布、几何分布,分析各种解码方法、序列解码方法及其各种改进,研究基于有限状态机的解码方法与其他信道码构成的迭代式联合解码方法,并展望目前联合信源信道算术码研究存在的问题及其前景。Encoding method of adding forbidden symbol of Joint Source Channel Arithmetic Codes（JSCAC） is introduced. Error detection theory of JSCAC is demonstrated. Error detection delay distribution of JSCAC, geometric distribution is reviewed. Main decoding methods are analyzed and compared, sequential decoding method and its variants, decoding based on finite state machine and iterative decoding method based on JSCAC concatenated channel codes. Various problems in exiting decoding methods are pointed out. Problems of present researches on JSCAC are analyzed. The prospect of JSCAC is given.
