    Abstract

    Based on the particular structure of parity check matrix (PCM) of LDPC codes in WiMAX and WiFi wireless communication standards, a new early stopping criterion (SC) is proposed to save the unnecessary decoding iterations. By using the proposed SC, decoding process will be stopped if all the information bits in a code word are corrected even if there are still some errors in the redundant (parity) part. Simulation shows that our proposed SC outperforms previous ones on decoding speed evaluated by average iteration number (AIN) with no bit error rate (BER) performance loss.
