    Abstract:

    A new method of LDPC product encoding and decoding by using the LDPC codes as component code is proposed. On the one hand, a low bit error ratio is obtained compared to the BCH product codes using binary extended BCH codes as component code. On the other hand, long LDPC codes are formed with short LDPC codes in the form of product codes, lowering complexity of long LDPC codes encoding. The simulation result shows that at low SNR, the bit error ratio of LDPC product codes is lower than that of the BCH product codes, at high SNR, the bit error ratio of LDPC product codes is higher than that of the BCH product codes. The same result is obtained compared with the same long LDPC codes. So the LDPC product codes are effective at low SNR.
