Abstract

Selection diversity (SELDIV), in which the best of N channel outputs is selected, provides significant diversity gain for digital communications over fading channels. Classical SELDIV analysis assumes that the best channel is immediately selected, implying no constraint on the switching rate of the system. We obtain an exact result for the average BER, as a function of the time since the last switch. Our results assume BFSK modulation and Nakagami (1960) fading with an arbitrary correlation function, treating Rayleigh fading as a special case.

切换约束对选择分集性能的影响

选择分集(SELDIV)，在N个信道输出中选择最好的，为衰落信道上的数字通信提供显著的分集增益。经典的SELDIV分析假设立即选择最佳信道，这意味着对系统的切换速率没有约束。我们得到了平均误码率的精确结果，作为自上次切换以来时间的函数。我们的结果假设BFSK调制和Nakagami(1960)衰落具有任意相关函数，将瑞利衰落作为特殊情况。
