本文给出了平稳非遍历信源编码的两个结果。第一个是信源编码定理，指出存在可变速率码，其性能任意接近于稳态非遍历信源的率失真函数。二是匡威信息传递定理。结果表明，当信源在容量为C的信道上传输时，所产生的失真不小于速率为C的固定速率码所能达到的最小失真。
Two results on the coding of stationary nonergodic sources are presented. The first is a source coding theorem stating that there exist variable-rate codes with performance arbitrarily close to the rate-distortion function of the stationary nonergodic source. The second is a converse information transmission theorem. It is shown that the distortion which results when the source is transmitted across a channel with capacity C is no less than the least distortion achievable by fixed-rate codes with rate C .
