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。-intertwined coding is a channel modification techniques, it will be designed to signal through an unexpected error originally belonged to the memory channel transformation is essentially independent of the random errors unmarked Recalling Channel. Coding intertwined as to overcome sudden fading channel interference effective way and the other is usually used to correct errors without memory of the independent channel coding combined constitute cascade code, Contemporary widely used mobile communications.
