交织编码是一种信道改造技术，它通过信号设计将一个原来属于突发差错的有记忆信道改造为基本上是独立差错的随机无记忆信道。交织编码作为克服衰落信道中突发性干扰的有效方法，通常和其它用于纠正无记忆独立差错的信道编码相结合构成级联码，广泛应用于当代移动通信。

-Channel interleaved coded is a transformation of technology, which belongs to the original signal design will be a burst error channel with memory is basically a transformation of independent random error channel without memory. Overcome the fading channel interleaved coded as an effective method of sudden disturbance, usually independent of other for no memory error-correcting channel coding concatenated codes combining form, are widely used in modern mobile communications.
