Abstract:

In the study of low-density-parity-check (LDPC) codes, most researchers are interested in their bit error rate performance. However, block error rate (BLER) is another important measure of the system performance because it provides the rate at which the blocks/packets need to be re-sent again - the smaller the better. In this paper, we apply a simple feedback technique to the decoding of LDPC codes. Extensive simulations have been performed. Results show that the proposed method can effectively improve the BLER of the codes at the waterfall region while not degrading the BER performance at the high SNR region
