An efficient rate-compatible (RC) puncturing scheme for LDPC codes is proposed, which tries to distribute the punctured bits as evenly as possible while maximizing the number of 1-SR nodes in Tanner graph. The puncturing scheme can produce RC LDPC with rates ranging from the mother code rate through even 1. Simulation results show that the new puncturing method is superior to random puncturing and the method in [2].
