| 摘 要： | 本文以一个典型移动数字信道为背景,利用已建立的三状态Markov模型参数求得在无交错和有交错两种不同情况下的信道错误分布概率P(n,m)和P_I(n,m);根据目前在移动数字信令中常用纠错码的对偶码的重量分布,利用了Macwilliams恒等式,计算出了这些码的重量分布A_i,最后由得到的A_i、P(n,m)和P_I(n,m)结果对有无交错两种不同情况下移动数字信令纠错码的检纠错能力进行了分析计算.

| Abstract: | In this paper, the parameters of the model obtained from Three-state Markov model in the digital mobile channel are used to calculate the error distribution probability of the mobile channel. Two cases are considered, namely, the block signalling coding with and without interleaving. The error distribution probability P(n, m)without interleaving and P_1(n, m) with interleaving are obtained by use of the parameters of the model. The weight distributions A_i of some signalling codes often used in digital mobile signalling systems are calculated in terms of the weight distribution of their dual codes and then, the performance of error-correction and error-detection of block signalling codes with and without interleaving are given by A_i, P(n,m)and P_1(n,m). |
