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.
In this paper, based on a typical mobile digital channel, the probability distribution of channel errors P (n, m) and P_I (n, m) in two different cases of non-interleaved and interleaved are obtained by using the established three-state Markov model parameters. ; According to the weight distribution of the dual code currently used in mobile digital signaling commonly used error correction code, using the Macwilliams identity to calculate the weight distribution of these codes A_i, finally obtained by the A_i, P (n, m) and P_I n, m) Results The error correcting capability of mobile digital signaling error correction code in two different cases with or without interleaving was analyzed and calculated.
