该文对turbo码中关键的交织器作了分析，阐述了交织器在turbo码中的重要作用，提出了一种基于ICMIC映射的随机交织器设计方法。通过在AWGN信道下采用Log-MAP译码算法进行仿真实验，本文设计的混沌交织器纠错性能较3GPP标准交织器提高0．35 dB，较S-伪随机交织器提高0．15 dB。

This paper introduces that interleaver plays an important role in turbo code theory .The selection of interleaver is the key to increase bit error rate performance .A new designing method of a random interleaver based on the ICMIC chaos mode is proposed .Simulated under Log-MAP algorithm over AWGN channel in the same condition, the average improvement is 0.35 dB when compared with 3GPP interleaver, and 0.15 dB compared with S-random interleaver .
