摘要
以联合编码的观点讨论了离散平稳各态历经信源及离散无记忆信道的联合编码系统实现无失真可靠通信的充要条件。结果表明:当考虑了信源因素的影响之后,系统可比通常情况下具有更高的传信效率。信道编码定理的结论只是本文结论的一个特例。
In view of joint source-channel coding, a joint coding theorem for ergodic discrete source and discrete memoryless channel is presented. The conclusion of the channel coding theorem is only a special case of this paper. It is shown that a higher coding efficiency could be available if the source and the channel are considered jointly.
