提出了一种用于中距离水声通信的m波段扩频调制（MCSS）。MCSS的方法是在发送端使用多个不同的啁啾信号来表示消息，在接收端使用一组相关器来解调消息。MCSS应用于UWA通信有三个优点：抗多径干扰和信道衰落性能好，数据传输速率高，鲁棒性好，处理增益大。湖面实验结果表明，在25 km距离内，MCSS的数据速率可达300 bps，误码率低于10-4。
M-ary chirp spread spectrum modulation (MCSS) for medium range underwater acoustic (UWA) communication is proposed in this paper. The method of MCSS uses M-ary different chirp signals to represent message at the transmitter and a bank of correlators to demodulate the message at the receiver. There are three advantages for MCSS applied to UWA communication: good performance against multipath interference and channel fading, higher data transmission rate with robustness and larger processing gain. Experimental results in the lake show the efficiency for MCSS that is in the distance of 25 km, the data rate can reach 300 bps with BER below 10-4.
