摘要

利用傅氏分割马尔可夫链对移动信道和静止信道的误差序列进行建模，得到了实时测量的实验和分析结果。采用FSK、DPSK、QPSK和8元PSK四种调制方案，将马尔可夫链信道模型应用于系统。利用实验测量和信道模型得到的误差分布，研究了不同块长度和信息率的BCH和Reed-Solomon纠错码。给出了不同交错深度对块错误率的影响。

Modelling of frequency hopped VHF channels in an urban environment and error correction on the channel

Experimental and analytical results of applying Fritchman partitioned Markov chains to model the error sequences of mobile and stationary channels are obtained from real-time measurements. The Markov chain channel models were applied to the system using four modulation schemes, namely FSK, DPSK, QPSK and 8-ary PSK. Using error distributions obtained from both the experimental measurements and the channel models, BCH and Reed-Solomon error correcting codes of various block lengths and information rates are investigated. The effect of different interleaving depths on the block error rate is shown.<>
