| Abstract: | 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. |
