摘要
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。
By analyzing the Hamming weight distribution on different puncturing points due to puncture period, this paper revealed the importance of puncture period, and got to the conclusion that puncturing period was a key factor responsible for the improvement brought by puncturing pattern selection. This conclusion was supported by the simulation result, and it was instructive in the search of optimal puncturing pattern.
