一个直扩同步的模块，用于伪码的捕获和多普勒频移的提取(A synchronous DS module for pseudo-code capture and extraction of Doppler frequency shift)

说明：  基于matlab GUI的数字滤波器源程序(The digital filter based on source code matlab GUI)

随机共振模型是检测微弱信号，近期流行的算法，效果不错，从事微弱信号检测和提取的可看下(Stochastic resonance model is to detect weak signals, the recent popular algorithms, good effect, engage in weak signal detection and extraction can look)

内含costas环代码与simulink 结合起来理解比较好(Containing the costas ring code and simulink combine better understanding)

MATLAB simulation results of BPSK, QPSK, 8-PSK and 16-QAM techniques of modulation in AWGN channel and fading channel

4 QAM Spatial modulation with maximum likehood detection

cofdm的MATLAB程序，包括完整框图及各部分的模块连接，方便学习~(cofdm Simulink)

正弦信号产生一个具有两个正弦信号向量，本设计中运用continuous-state space s-function模块对输入信号进行变换，并通过scope模块显示出来。压缩文件中提供了M文件s-function的编写，以及搭建的模型框图(Generate a sinusoidal signal with two sinusoidal signal vector, the design of the use continuous-state space s-function module to transform the input signal and display module through the scope. Zip file provided in the file s-function M in the preparation and structures of the model diagram)

说明：   用MATLAB语言编写的程序，称为M文件。M文件可以根据调用方式的不同分为两类：命令文件(Script File)和函数文件(Function File)。(Language with the MATLAB program, called the M file. M files can call the different ways into two categories: command file (Script File), and function files (Function File).)
