摘要
水声通信是以声波信号作为载波的水下通信,水声信道是水下通信的重要组成部分.在浅海中,水声信道是通信环境恶劣的信道,存在着较强的频率选择性衰落.通过对浅海水声信道的分析、建模、仿真,验证了水声信道的频率选择性衰落.
The underwater acoustic communication is the underwater communication adopted the acoustic signal as its carrier,and the underwater acoustic channel is an important part of the underwater acoustic communication.However,the channel is a bad communication channel in the shallow sea and there is strong frequency selectivity attenuation.Based on the analysis,modeling,simulating,the frequency selectivity attenuation of the underwater communication channels was proved.
