摘要
以三状态 Markov 模型作为移动信道长突发误码的概率模型,从模型参数与差错统计量之间的关系入手,分析、讨论了既能描述移动信道的误码特征、又能为纠错码参数的选择提供参考的错误分布概率 p(n,m);对 BCH 分组码在交错与非交错两种不同情况下的纠错性能进行了估计。理论估计与计算机模拟结果取得了令人满意的一致性。
In this paper,the Markov model with,three states is employed for the probability model in the mobile communication channel with long burst error.The error distribution probability p(n,m)for the mobile channel is calculated in terms of the relation between the parameters of the model and the error statistical parameters.The performance of error-correcting interleaved and no interleaved BCH codes are estimated,which can be applied to the mobile communication channel and the theoretical estimation results are very close to the results of computer simulation.
