FH-FSK Underwater Acoustic Control and Communication System Based on LDPC Code

Article Preview

Abstract:

In this paper, a frequency-hopping frequency-shift keying (FH-FSK) underwater acoustic control and communication system based on Low Density Parity Check Codes (LDPC) is proposed by combining with FH-FSK system and LDPC. The anti-jamming performance of the system in the condition of Gaussian white noise and coherent multi-path channel is simulated respectively. The simulation result shows that FH-FSK system based on LDPC has a better performance than that of convolutional code. Therefore, it is more applicable for the system to have a stable anti-jamming performance and better robustness.
