在数字通信系统中，信源编码是为了提高有效性，信道编码是为了提高可靠性，而在一个通信系统中，有效性和可靠性是互相矛盾的，也是可以互换的。

我们可以用降低有效性的办法提高可靠性，也可以用用降低可靠性的办法提高有效性。

本文对信源编码和信道编码的概念，作用，编码方式和类型进行了解析,以便于更好的理解数字通信系统的各个环节。

In munication system, the source coding is in order to improve the effectiveness, channel coding is in order to improve the reliability, and in munication system, effectiveness and reliability is contradictory, is also can be interchanged. We can use to reduce the availability of improving the reliability, also can use to improve the effectiveness of reduces reliability. In this paper, the source coding and channel
