Ｔｕｒｂｏ码是近年来信道编码理论研究的热点课题，而交织器的设计对Ｔｕｒｂｏ码的性能有很大的影响．本文介绍了一种Ｔｕｒｂｏ码交织器性能的分析方法，并对以（７，４）汉明码为分量码，交织长度为１６的（４０，１６）Ｔｕｒｂｏ汉明码作分析，给出理论分析及采用文献［２］的迭代方法的计算机仿真实验的结果，由此证实了这种方法的有效性．仿真结果还表明，文献［１］的评价交织器性能的方法比文献［３］的方法更可靠，说明传统的以相关系数来评价交织器性能的方法有局限性，不一定能应用到Ｔｕｒｂｏ码之中来． Turbo codes are the hot topics in the research of channel coding theory in recent years, and the design of interleaver has a great influence on the performance of Turbo codes. This paper introduces a method to analyze the performance of Turbo code interleaver, analyzes the (40,16) Turbo Hamming code with (7,4) Hamming code as component code and interleave length as 16, and gives the theoretical analysis and adoption The results of the computer simulation of the iterative method in [2] confirm the validity of this method. The simulation results also show that the method of literature [1] for evaluating the performance of an interleaver is more reliable than the method of [3], which shows that the traditional methods of evaluating the performance of an interleaver with correlation coefficients have limitations and may not be applied to Turbo codes Among them.
