| 摘 要： | 针对Turbo码编译码结构的交织器的设计问题,提出了一种有效降低突发错误的交织器的设计方法,利用了混沌序列的伪随机性,结合Dithered Relative Prime(DRP)的内部交织过程,并将其应用于Turbo码中,和传统交织器在相同环境下进行仿真比较.结果表明:在信噪比大于1.5 dB条件下,该交织器有效地降低了Turbo码的误比特率,达到改善系统性能的目的.

| Abstract: | Since the design of interleaver of Turbo code is a crucial problem in coding and decoding structure in Turbo code,by analyzing the requirements of Turbo code on its interleaver,and combining with Dithered Relative Prime(DRP) of the process of interal interleaver,a new approach of interleaver using pseudo randomness of the chaos sequence is proposed and applied in Turbo code in order to reduce effectively unexpected errors.By simulating in comparison with the traditional interleavers in the same environment,... |
