摘　　要：本文介绍了四种信道估计插值算法,采用实验室自行研制的水声通信系统硬件平台,进行了海洋试验,实验结果表明线性插值法等四种插值算法用于基于导频信道估计的OFDM水声通信是切实可行的,并比较了四种插值算法对通信效果的影响。The paper introduces four inserting-values arithmetic of channel estimation, implements the experiments in the sea based on UWA OFDM system which designed by our laboratory. The results shows that these inserting-values arithmetic adapted in UWA OFDM system which based on different pilot signals is feasible.In additon,the paper compares the influence of these four inserting-values arithmetic for communication effect.
