【Abstract】 An introduction to the conception of underwater acoustics communication networks is briefly presented. Multiple access technique is discussed. A robust frequency-hopping code division multiple access (FH-CDMA) scheme is proposed for shallow sea acoustics communication networks. The performance of this scheme is analyzed and compared in different underwater acoustical channel environments by designing a network simulation system based on underwater acoustical channel model. Simulations results show the robust performance of this scheme in the shallow sea multipath fading channel.更多还原
