摘　　要：在总结已有TURBO码交织器设计规则的基础上,设计出一种新的交织器———综合型随机交织器.通过计算机仿真,从输出码重、相关系数和延时3个方面性能对常用交织器和新交织器进行了比较.结果表明,综合型交织器获得的纠错性能优于其它交织器的性能.Based on the discussion about the role and old criterion of interweaver in Turbo codes, a new design method of random interweavers is proposed. By computer simulation, the performance of the new interweavers is compared with other interweavers in aspects of codes-weight for output, correlativity and time delay. The result shows that the error correction feature of this interweaver is better than others.
