    Abstract
  • According to the characteristics of time-varying and intensive multipath of underwater acoustic (UWA) channel, a UWA channel model with time-varying fading, multipath interference and additive white Gaussian noise (AWGN) is established. Based on the channel model, a UWA frequency-hopping communication system using noncoherent multi-frequency shift key (MFSK) modulation is designed, and the simulation methodology is described. Simulation results of the system performance under Rayleigh fading channel and Rician fading channel are achieved and analyzed to provide a reference for parameters selection and performance optimization of FH/MFSK system. The results show that the proposed communication system can effectively suppress the multipath interference, and has certain immunity to Doppler spread, therefore reliable underwater acoustic communication can be implemented with the communication system.
