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。
Four kinds of channel estimation interpolation algorithms are introduced. Under the ideal hydrological conditions, the actual pool experiment is used to verify that four kinds of interpolation algorithms such as linear interpolation are feasible for OFDM underwater acoustic communication based on pilot channel estimation. The effect of four kinds of interpolation algorithms on the communication effect.
