摘　　要：信道是构成通信系统的重要部分,用来传输和储存信息,而信息在信道中传输的多少不仅仅与信道本身的特性有关,还和信源的输入有关。讨论了信息论中的强对称离散信道,并给出其信道容量的一种算法,得出只有离散信源的输入呈等概率分布时,此时强对称离散信道才可以达到其信道容量.Channel is an important part of a communication system,which is used to transmit and store information,and information in the channel is not only associated with the characteristics of the channel itself,but also related to the input,in this paper,the strong asymmetric information theo-ry is discussed in detail,and an algorithm is given,it concluded that when the input of discrete in-formation source in probability distribution,the symmetric discrete channel can achieve the chan-nel capacity.

关 键 词：强对称离散信道 信道容量 平均互信息量
