| Abstract: | 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. |
