| 摘 要： | 为了提高高速并行Turbo译码的效率,Turbo码需要改进其内部交织器。QPP（Quadratic Polynomial Permutation）交织器是一种新型的基于置换多项式的确定性交织器,由于其操作简便,复杂度低,结构灵活,性能优良,成为近年来Turbo码交织器研究的热点。分析了QPP交织器的原理,通过实验验证了QPP交织器及其反交织器具有最大无争用特性,该特性可以有效提高高速分块并行Turbo译码的效率。仿真结果表明,QPP交织器还可以显著改善高速分块并行Turbo译码性能。

| Abstract: | QPP（Quadratic Polynomial Permutation） interleaver is a new deterministic interleaver based on permutation polynomial,and it has become the hotspot of interleaver researching in Turbo coding because of its easy operation,low complexity,flexible structure and excellent performance.This paper analyzes the principle of QPP interleaver,and verifies both QPP interleaver and its inverses with the maximum contention-free feature that can improve the efficiency of high-speed sub-blocks parallel Turbo decoding.Simulation results show that,QPP interleaver can also significantly improve the performance of high-speed sub-blocks parallel Turbo decoding. |
