准对称信道信道容量的证明及其Matlab实现

Proof and Matlab Simulation of the Para-Symmetry DMC Capacity

信道容量表示信道传输信息的最大能力。本文介绍了什么是离散准对称信道,给出了其信道容量的证明过程,最后通过Matlab实现了信道容量的计算,结果表明当输入的每一个符号的概率都相等时达到信道容量,符合实际,并对加深信道理论的理解有一定的参考价值。

Channel capacity represents the maximum capacity of the channel to transmit information.This paper introduces what is the discrete para-symmetric channel and gives the proof process of its channel capacity.Finally the calculation of channel capacity is realized by using Matlab.The results show that the channel capacity can be reached when the probability of each symbol input is equal.This conclusion is consistent with the reality and has certain reference value for the understanding of the channel theory.
