摘　　要：Turbo码中交织器性能的优劣将直接影响到Turbo码的译码性能。在分析交织器的设计准则和类型的基础上,利用m序列的遍历性,设计了一种基于m序列的随机交织器,并给出了基于FP-GA的硬件实现方案。仿真结果表明,该随机交织器在实现输入数据随机分布方面性能优异,并降低了Turbo码的译码延迟。The performance of interleaver in Turbo codes directly affects the Turbo decoding performance. Based on analysing the design rules and types of interleaver,a random interleaver is designed by taking advantage of the ergodie property of m sequence. The implementation based on FPGA is given. The simulation result shows that this random interleaver can excellently randomize the input data and also reduce the decoding delay of Turbo codes.
