Abstract :
Concerning the high encoding complexity of low-density parity-check (LDPC) codes, a joint generator and parity-check matrices parallel encoding method is proposed, which is able to take full advantage of the characteristics of the sparse parity-check matrix, such as cyclicity and equality of row weight. Experimental results show that, the proposed method runs fast and requires less memory due to low computational complexity.
