Abstract: This paper presents a new chaotic interleaver algorithm which uses the choatic mapping as permutation mode. Using the SOVA decrypted algorithms made numerical simulation over the AWGN channel. Under the same conditions, the simulation results of our chaotic interleaver are compared with the standard 3Gpp interleavers as well as the random interleavers. The results show that performances of chaotic interleavers are better than or equivalent those of random interleavers and 3gpp standered interleavers.

Key words: chaotic interleaver, pseudo-random interleaver, 3Gpp standered interleaver, soft output iterative decoding, non-systemic convolutional codes

摘要: 本文提出了基于混沌理论的交织器的设计方法, 利用混沌映射得到的交织方式实现混沌交织器。 在AWGN(加性高斯白噪声)信道下采用SOVA译码算法进行仿真, 在相同条件下将混沌交织器和3Gpp标准交织器、随机类交织器的仿真结果进行比较。仿真结果表明在中长帧传输过程中, 混沌交织器的性能不亚于以上两种交织器。
