摘要

给定两个相关的衰落信道上的数字传输,我们提出了一个易于计算的表达式,用于紧逼近每个信道上符号错误概率之间的相关性。对于瑞利衰落信道,表达式是精确的。该相关表达式可用于衰落系统的误差性能分析,特别是多信道系统和误差事件的马尔可夫建模。作为一个例子,我们使用这些表达式来约束OFDM系统的块错误率

Simple Expressions for the Correlation between Fading Channel Error Rates
Given digital transmission over two correlated Rician fading channels, we present a readily calculable expression for a tight approximation to the correlation between the probabilities of symbol error on each channel. For the Rayleigh fading channel the expression is exact. This correlation expression has applications in error performance analysis of fading systems, particularly multichannel systems and Markov modelling of error events. As an example we use these expressions to bound the block error rate of an OFDM system
