According to the character of underwater acoustic channel, MIMO system is used in underwater acoustic channel taking the advantage of improving channel capacity, and providing MMSE - DFE equalzer to reduce the effect of ISI in the receive end.

• 针对水声信道特性,提出了在水声信道下利用MIMO技术提高信道容量,并在接收端进行MMSE-DFE均衡来消除符号间干扰(ISI)。
