Abstract
In this letter, a parity check based iterative IC scheme is proposed for LDPC coded MIMO systems. After the decoding procedures in each iteration of the proposed scheme, each decoded codeword is utilized for the IC procedures only when the ratio of the check nodes satisfying the parity check equations to the total number of check nodes is not smaller than the pre-defined threshold value. Simulation results verify that the proposed scheme can achieve an improved BLER at the high SNR region compared to the conventional iterative IC scheme.
