提出了两种新的交织方案 ,即均匀分布的伪随机交织与Rayleigh分布的伪随机交织 .并对采取这两种交织方案的BCH(63 ,3 9,4 ) ,BCH (1 2 7,78,7)码在移动衰落信道下的纠错性能进行了计算机仿真 ,且与周期交织方案的结果作了比较。仿真结果表明 :在对误码率要求不高时 ,采用伪随机交织方案可减少平均时延 ;同时伪随机交织方案也具有加密功能 Two new interleaving schemes are proposed, that is, pseudo-random interleaving of uniformly distributed pseudo-random interleaving and Rayleigh distribution, and the BCH (63,39,4), BCH (1 27,78 , 7) code error correction performance in mobile fading channel were simulated by computer and compared with the result of periodic interleaving scheme. The simulation results show that the pseudo-random interleaving scheme can reduce the average delay when the BER requirement is not high, and the pseudo-random interleaving scheme also has the encryption function
