Abstract
The excellent error correction performance of Low-Density Parity Check code has made it widely used in many modern communication systems. In time-varying fading channels, multiple sets of codecs with different code rates are often used to adapt to different states of the channel. And rate-compatible coding is an effective implementation of the problem. This paper proposed an improved centralized puncturing algorithm applied to irregular LDPC. And the proposed algorithm is verified by comparing the performance of punctured LDPC codes with CCSDS standard and Ma Fuli’s algorithm.
