摘要
基于Rice－Lognormal联合分布的两种信道模型，定性地分析了移动卫星信道中的MP－SK－TCM恃性。推导出了适合这两种模型的Chernoff界和另一种新的特性界表达式，计算了8U-TC－MPSK方案的误比特概率。计算机模拟显示出，本文得到的特性界不仅简单、方便，而且比已有的界紧，能够较好地反应这类信道的TCM特性。
In this paper,tbe analytical performance bounds of MPSK-TCM are presented over mobile satellite channels. Chernoff bound and another new performance bound are derived based on the statistical model of Rice-Lognormal combinative distribution,and the bit error probability of SU-TC-MPSK schemes is computed.The simulation shows that performance bounds derived in this paper are simple and tighter than those available,which is agreement with the characteristic of practical mobile satellite channels on TCM.
