摘要
从码重分布的角度分析了影响Turbo码性能的原因,介绍了Turbo码最优周期交织器的概念,为Turbo码提供了一种新的交织器设计方法。经实验验证,用提出的方法所设计的交织器具有较好的性能,易于实现。
From the point of view of the distribution of code weight, the factors affecting the quality of Turbo codes are analyzed, the concepts of optimal periods interleaving implement for Turbo codes are introduced, and a new design of interleaving implement for Turbo codes is provided. The experiment proves that the interleaving implement designed by using the proposed method has better functions and can be easily realized.
