摘　　要：信道容量描述了信息无失真传输最大容量,是信源编码的重要依据。文章介绍了离散无记忆准对称信道及其信道容量,分析了达到其信道容量的输入概率条件,给出了基于MATLAB的仿真实验验证过程,验证了在输入等概率条件下获得信道容量,对学生加深信道论的认识有一定的参考意义。The channel capacity describes acommunication channel transporting the biggest capacity with no distortion. It is the important basis when coding the source letter. The paper Introduces Para-symmetry DMC and analyzes the condition which attains the capacity of Para-symmetry DMC. Through emulator based on MATLAB software, ttsetifies the conclusion about what can attain the biggest transport rate when all inputing symbols having an equation of probability. It is recommendable to students in learning the theory of information.

关 键 词：信道矩阵 可排列 信道容量 准对称信道
