QPP内交织器的架构设计与实现

Architecture Design and Implementation of a QPP Internal Interleaver

为达到较高的吞吐率,在Turbo码并行译码时,需采用二次置换多项式(QPP)内交织器。通过理论分析,提出一种新的QPP内交织器实现方法与架构。相比现有的实现方法,提出的实现方法复杂度降低,计算简单,资源占用减少。软件仿真结果证明了该方法的正确性。

In order to get a high throughput, QPP（Quadratic Permutation Polynomial） inner interleaver is adopted for Turbo parallel decoding. Through theoretical analysis, a new implementation method and architecture is proposed. Compared with the existing method, the proposed method can reduce the complexity and resource consumption and is easily calculated, and simulation result shows that this method is correct.
