摘要
水声信道建模在仿真预测通信系统性能方面作用显著,可以大大降低海试成本。文中基于射线理论模型,建立了两种常用的水声信道模型:相干多途信道模型和时变信道模型,模型从某种程度上反映了水声信道的主要特点,虽然其特性与真实信道特点有一定差距,但并不影响其在水声通信性能估计方面的应用。
Modeling the underwater acoustic channel（UAC）is useful for prediction of a system performance via simulation and thus avoiding expensive ocean experiments.Based on ray theory,two traditional models are proposed,including coherent multipath channel model and time varying channel model.Although they are still not perfect compared with real channel,it didn＇t hinder their application on performance predict of communication system because it＇s really reveal some characteristics of underwater acoustic channel.
