Abstract

The Low-Density Parity-Check Codes (LDPC) become the most important channel codes used to address the huge Bit Error Rate (BER) stim from highly new mobility of the next generation. An iterative decoder of LDPC which employed many algorithms that are different according to their performance and complexity. Logdomain decoder is one the most technique involve for LDPC decoding according to its better performance and acceptable complexity. In this research, a system including Logdomain decoder is simulated and evaluated in terms of BER against SNR. The results show that such decoder with optimum parameters is better than hard decision decoder which needs only half the amount of SNR that consumed by hard decision.
