英文摘要	Considering that a shallow water acoustic (SWA) channel is characterized by rapid time-dispersive fading, multipath and narrow bandwidth, which has to use the error correcting code technique with short code length, good performance and easy implementation to improve the reliability of its communication system, the quasi-cyclic low density parity check (QC-LDPC) coding as an error correction coding scheme was applied to SWA channels. A system simulation model including QC-LDPC codes for the SWA channels was built. With the decoding algorithm of belief propagation (BP), the performance of the system was simulated over a typical three-multipath SWA channel under different code rates and girths. The performance comparison of QC-LDPC codes in different SWA channels was presented. A channel model was established according to the characteristic of the SWA channel environment in Xiamen harbor. The model was used to simulate the performance of QC-LDPC codes. The simulation results show that simple QC-LDPC codes can achieve almost the same performance of the random (3, 6)-LDPC codes, which proves the effectiveness and the good application prospects of QC-LDPC codes in SWA communication.
