交织可以使信道的突发错误转化成随机错误，是通信过程中的一个非常重要环节。实际应用中，交织类型非常之多，但最典型的类型主要有矩阵交织、卷积交织，和存储器交织，深刻了解交织原理的最好方式是对其仿真算法的实现，本算法来自卫星通信一线技术人员，非常精炼，值得通信同行借鉴。(Interleaving can make the burst error of the channel be transformed into random error, and it is a very important step in the communication process. In practical application,too many interleaving types are exist, but the most typical types are matrix interleaver, convolutional interleaver, and ram interleaver, the best way of understanding interleaver is to realize it with simulation algorithm, this algorithm is very refined, worthy of reference for communication.)
