OFDM simulation system use different modulation technique such as M-PSK M-QAM user can select that type . the program use image to be transmitted in QI mapped ,signal affected by AWGN and Fading on channel be for received

说明：  可用于matlab等绘制中国地图，即开即用，十分方便(It can be used in Matlab to paint a beautiful China Map.)

说明：  关于对卫星导航电文进行位置计算，输出卫星的位置(on satellite navigation messages location, the location of satellite exports)

说明：  该程序模拟了海浪的三维动态仿真，展示了随机海风作用下，波浪的运动。(The program simulates the three-dimensional dynamic simulation of ocean waves)

一个关于bp算法的大全，有matlab、c、c++的源代码都有，还有bp神经网络源程序，感兴趣的就看看吧(an algorithm on the Encyclopaedia bp, Matlab, c, c have the source code, there bp neural network source, interested to see it on)

整个OFDM的matlab仿真代码，使用16qam调制，还有word的文档，讲解很细(The OFDM matlab simulation code, the use of 16 qam modulation, and word document, very fine )

变步长的LMS滤波器设计，一种新的变步长LMS自适应滤波算法(Design of variable step size LMS filter, a new variable step size LMS adaptive filtering algorithm )

自己需要给出坐标，GPS测距。主要是实现了基于maltab测距GPS测距原理(you should give coordinates, GPS ranging)

和芯星通um220指令协议，适合于单片机开发(Protocol Specification of UM220 Unicore GPS/BDS module)

次程序用来仿真线性调频脉冲下的一维距离像，可以对比压缩前后的目标回波信号(Second program is used to simulate the next chirp like a one-dimensional distance, you can compare before and after the target echo signal compression)
