浅海远程水声通信由于水声信道带来的严重多径干扰和衰落, 导致通信速率低、误码率高
以及接收端信噪比低等缺点。针对这一问题, 提出了一种比较有效的M 元线性调频(L FM ) 水声通
信技术。(Remote shallow water acoustic underwater communication channel because of the serious multi-path interference and fading, resulting in lower communication rate, error rate
And the receiver signal to noise ratio and low defects. To solve this problem, we propose a more effective M-ary linear FM (L FM) acoustic communication
