This is ieee paper describes OFDM radar implementation, good for study and understanding

多普勒连续波雷达在matlab上的测速程序，实现测速效果(Matlab FMCW radar speed measurement procedures)

这是看完一本通信仿真手册后我自己写的一点程序，包括ASK FSK PSK的调制和解调程序，不过是比较简单的 ，因为用了公式的()

说明：  维纳滤波matlab代码，对语音去噪有较明显效果，可做去噪算法借鉴(Wiener filter matlab code,It has obvious effect on speech denoising and can be used for reference in denoising algorithm)

基于RSSI测距的等边三角形定位算法,对研究无线传感器网络定位算法十分有用(RSSI-based location of an equilateral triangle positioning algorithm, the study of wireless sensor network localization algorithm is very useful)

51MODBUS从机程序源码希望对有用的人有用，，(51MODBUS,welcom to here,thank you very mouch.)

模拟调制识别各特征参数随信噪比变化曲线。信号的瞬时信息包括瞬时幅度、瞬时相位、瞬时频率及其不同角度的统计特征值，其中瞬时幅度、瞬时相位、瞬时频率是一个信号最基本的特征。（AM、DSB、SSB、VSB、FM、AM-FM）(Simulated Modulation Recognition Curve of Variation of Characteristic Parameters with Signal-to-Noise Ratio)

说明：  td_scdma的完整程序，包括发送和接受两部分，涉及信道编解码，交织，扩频等(td_scdma complete process, including sending and receiving two parts, related to the channel encoding and decoding, interleaving, spreading, etc.)

产生复高斯的白噪声,这和matlab 自带的不一样，容易理解，但是经对比还是和自带的有区别的(AWGN noice we are very nice. please try to run it snd you will find you are good too.)

说明：  MATLAB实现COSTAS环的源程序，有详细的注释说明 (costas source matlab)
