摘要
提出了一种新型交织器 ,对其完备性从数学上作了证明 ,进行了计算机仿真 ,分析了仿真结果 ,并与其它交织方案的性能作了比较 .结果表明 ,该交织器实现简单 ,性能要好于复杂度类似的其它交织器 .文章还对进一步改进本交织方案提出了建议 .
A new interleaving scheme for turbo codes was devised and a mathematical proof to its completeness was given. Through computer simulation in MATLAB, its performance was shown and analysed. Compared with other types of interleavers, the interleaver proposed here was implemented easily and its performance outperformed others with the roughly same complexity in structure and implementation. Suggestions were given to further improve the interleaving scheme.
