中文摘要: 在平均费用受限制的条件下研究信道的信息传输率等价于求解信道容量代价函数,在信道费用函数取特殊值和输入分布为等概分布时,N元强对称信道的信道容量代价函数C(F)取得极值且C(F)是关于F的上凸函数.
Abstract:The transfer rate of information is equal to solving the cost function of channel capacity when the average expense is limited.The cost function of channel capacity C(F) attains its extremum and is the convex function related to F while the N strong symmetric channel is equiprobability distribution for the expense function equal to particular value.
keywords: average tautomeric information transfer matrix channel capacity expense function N strong symmetric channel cost function
