  Abstract

In this letter, a pre-recovery scheme for punctured coded bits is proposed for LDPC coded systems. Before the iterative decoding process, the proposed scheme recovers bit messages of all punctured bit nodes according to the step recovery order through the sequential recovery procedures using survived check nodes of punctured bit nodes. Therefore, the proposed scheme can enhance the message propagation delay caused by the recovery of punctures bit nodes during the iterative decoding process. Simulation results show that, compared with the conventional iterative decoding without any pre-recovery procedures, the proposed scheme can enhance the error performance and decoding convergence speed as the number of punctured bit nodes increases.
