摘要
重点研究了低密度校验码(LDPC)和Turbo码在信息帧较短时的性能,以及在信息帧较短条件下如何在LDPC码、Turbo码和卷积码之间选择编码的问题。指出在短帧条件下,LDPC码与Turbo码有近乎相同的性能,但LDPC码比Turbo码更利于工程实现。
This paper investigated the performance of LDPC code and Turbo code and discussed the problem how to selecte LDPC code,Turbo code or convolutional code when information length of these codes are all short. This paper point out that LDPC and Turbo code have the same performance,but LDPC is more easy to implement than Turbo code.
