Abstract :
LDPC code is used in the underwater wireless communication system. Using regular (3,6) LDPC code, with LLR BP decoding algorithm, a simulation is completed in the underwater channel of constant speed of sound. The results show that: the bit error rate of 10-5 can be achieved at the signal to noise ratio of about 2.8 dB, which indicates the high-performance transmission under lower signal to noise ratio may be realized.
