摘要
本文对Turbo码中的关键组成部分——交织器作了分析,阐明了交织器在Turbo码中的重要作用;提出了一种基于Henon混沌模型的随机交织器设计方法。通过仿真实验,本文设计的交织器整体性能优于CDMA2000标准中Turbo码交织器性能,在高斯信道下,纠错性能平均改善0.15dB。
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 Henon Chaos mode is preposed. Simulation results show great magnitude of improvement in bit error rate (BER) performance compared to that of the Turbo codes used by the interleaver in accordance with CDMA2000 standard. The average performance improvement in AWGN channel is approximately 0.15dB.
