摘　　要：由于无线信道的高误码率和突发错误的特性,在无线ATM中必须使用有效的差错控制机制.交织的方法可以提高ATM信元的差错控制性能.文章基于标准的ATM信元结构,分析比较了几种不同交织方法的性能.仿真结果表明,在一定的交织深度下,ATM信元混合交织能获得较好的效果.In wireless ATM network, an efficient error control mechanism has to be used because of the high bit error rate and burst nature of bit errors. It＇ s clear that the interleaving method can improve the WATM error control performance. Here, an interleaving method called mixed-cell based on ATM is discussed and compared with the traditional strategies. Simulation shows that it has a better performance in proper interleaving depth.
