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 ICT. )

说明：  MIMO系统仿真 ＭＩＭＯ技术可Ｗ极大地提升系统吞吐量和有效抵抗多径衰落的影响，被视作ＬＴＥ的核也技术之一。信号检测模块又是ＭＩＭＯ系统中非常重要的一步，因为接收端收到的信号是经历了无线信道衰落影响的信号，与发送端发送的初始值之间差距较大，因此，在接收端首先应进行信道估计求出信道矩阵Ｈ，然后根据该信道矩阵的信息，从接收端还原出发送信号。因此，在ＭＩＭＯ系统中信号检测直接彰响着系统系能的提升。本章将先介绍高移动性ＭＩＭＯ无线信道的建模方法(simulation of MIMO-OFDM communication system)

在Microsoft Visual C++软件环境下，用C++ 语言实现整个仿真。将整个产生系统分为C/A码产生，信号产生，量化三个模块，经过编写和调制实现产生的基本功能，即输入导航电文及控制数据，例如 选取卫星信号，多 普勒频移，采样周期。最后可以得到加入服从高斯分布的噪声信号的数字离散中频信号。 (We use the C++ language to archive the simulation in the Microsoft Visual C++ circumstance. The entire generating system is divided into three parts,including C/A Code, Signal Generating and Quantizer. After writing codes and checking and confirming, I archive the basic functions. If you input the guiding codes and controldata like satellite selecting signal, Doppler frequency movement, sampling period, at last you can get the digital middle frequency signals with gauss distributing noise)
