摘要

本文推导出了ＲｉｃｅＬｏｇｎｏｒｍａｌ衰落信道中没有信道状态信息和具有信道状态信息两种情况下的最大似然译码度量，并同传统欧氏距离度量的成对错误概率进行了比较．数值计算结果表明：对于ＴＣＭＰＳＫ方案，信道衰落特征（ｆＤＴ）对度量特性的影响几乎可以忽略．最后，讨论了ＲｉｃｅＬｏｇｎｏｒｍａｌ衰落信道中的最小交织深度

Abstract

The maximum likelihood decoding metrics without and with channel state information are derived over Rice Lognormal fading channel.The pairwise error probability is compared with conventional Euclidean distance metrics.The numerical results show that :for TC MPSK signal

the effect of Channel fading characteristics （f DT） on metric performance is negligible.The minimum interleaving length required to optimize code performance over Rice Lognormal fading channel is also discussed.
