交织是一种以一一映射的方式随机化原始信息序列的过程。正是由于交织器对Turbo码性能的重大影响,所以对于交织器的研究也成为一个热点。目前为止,交织器的设计还没有统一的方法,因而也涌现了很多种交织器,如分组交织器、随机交织器等。 Interleaving is a process of randomizing the original sequence of information by one-to-one mapping. Due to the great influence of interleaver on the performance of Turbo codes, the research on interleaver has also become a hot spot. So far, there has been no uniform method for the design of interleaver, so many kinds of interleavers have also emerged, such as packet interleaver, random interleaver and so on.
