Time-varying channel model and transmission characteristics analysis
Based on the physical characteristics of underwater acoustic channel,the time-varying channel model and its transmission characteristics are studied in this paper.Based on the theory of ray acoustics,combined with the Doppler effect and multi-scale and multi-delay characteristics of time-varying channels,the time-varying underwater acoustic channels un-der the conditions of calm sea surface and sinusoidal undulating sea surface are simulated by VirTEX algorithm,and the transmission characteristics of the channels are analyzed by transmitting signals and receiving signals transmitted through the channels.That is,the channel has attenuation characteristics,multi-path effect and Doppler effect.
