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

GPS-simulation
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)
