考虑Turbo码的删截周期对汉明重量在删截位置上的分布的影响,得出删截方案的优选对性能的改善程度取决于删截周期的结论,最后通过计算机仿真进行了验证。这一结论对高码率Turbo码的删截方案的优选有重要的指导意义。
Considering the influence of the puncturing period of Turbo codes on the distribution of Hamming weight in the puncturing position, the conclusion that the optimal performance of the puncturing scheme depends on the puncturing period is obtained. Finally, the simulation is validated by computer simulation. This conclusion has important guiding significance for the optimization of puncturing scheme of high bitrate Turbo codes.
