摘　　要：在Turbo码系统中,交织器是非常重要的组成部件,交织器参数的识别对Turbo码分析识别技术的研究具有重要意义。针对Turbo码系统中双二进制形式交织器的两级交织方式,提出了采用码重分析法和列向量对比法相结合的识别算法。仿真结果表明,识别算法在接收序列大于10%误码率的条件下,能够对交织器进行有效识别,验证了算法在高误码率的情况下的有效性。Interleaver is such an important part of Turbo-code system that the recognition of interleaver parameters is of great significance to the analysis and recognition techniques of Turbo-code. For the two-level interleaving method of duobinary interleaver in Turbo system, the paper proposes a recognition algorithm that combinations code weight analysis and column vector comparison together. The simulation shows that the recognition algorithm can recognize the interleaver correctly when the receiving sequence has a BER higher than 10%, which validates the validity of the algorithm under high BER conditions.
