After convolutional encoding , the data is reordered by the interleaver. At the receiver , the data pass through deinterleaver for the purpose of dividing possible consecutive error bursts into inconsecutive code , so it can be corrected by convolutional decoding.

You can ap2 ply it to your own project only altering initial parameters.

交织编码在3G系统中已经大量使用，数据通过卷积编码后进行分组交织，在接收端完成反交织，将连续误码分散成非连续误码，从而使得误码在纠错允许的范围内得到纠正； CPLD 具有方便的在线编程功能，可以用来实现交织编码；考虑到矩阵交织器的多样性而设计的通用矩阵交织器，只须通过修改一些参数值即可实现不同的交织器，大大节省了设计时间。
