摘要
介绍了一种符合3GPP标准的交织器,通过仿真分析,比较了该交织器相对于普通随机交织器的优异性,以及在这种交织器下Turbo码在AWGN信道环境中的设计参数对误码率性能的影响。在详细分析3GPP标准交织器的基础上,对Turbo码的性能进行了仿真。结果表明,采用3GPP标准交织器可以改进误码率性能,而且译码性能也比较稳定。
An interleaver of 3GPP standard was discussed. By simulating analysis,the superiority of the interleave of 3GPP standard was compared with random interleaver. The parameters influence on the performance of the Turbo code in AWGN channel was also analyzed. On this basis ,the performance of Turbo code was simulated. The results show that adopting the interleaver of 3GPP standard can improve the performance of BER with stable decoding performance.
