摘　　要：介绍了四种信道估计插值算法,在较为理想的水文条件下,用实际水池实验验证了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。This paper introduces four inserting-values arithmetic of channel estimation.Under more ideal conditions,with the tests in the pool to test these inserting-values arithmetic is adapted in UWA OFDM system which based on different pilot signals is feasible,and compares the influence of these four inserting-values arithmetic for communication effect.
