在MATLAB中用Goertzel算法（先用FFT算法，再用goertzel算法，）仿真DTMF的产生与检测的程序。应用于双音多频信号的产生与检测。(in Goertzel algorithm using MATLAB (first using FFT algorithm, reuse goertzel algorithm) simulation DTMF detection with the selection process. Used DTMF signal detection with the selection.)

wcdma上行扰码生成，严格按照3gpp 25212进行编写，有多种实现方式(wcdma uplink scrambling code generation, in strict accordance with 3gpp 25212 to write, there are a variety of ways)

完整的带有多种参数的宽带雷达信号仿真和波形分析，给出了工作频率，调频带宽，脉冲重复周期、扫频时宽等参数，结果绘图显示，程序有中文注释，方便好用(Complete wideband radar signal simulation and waveform analysis with a variety of parameters, given the operating frequency of the FM bandwidth, pulse repetition period, when the sweep width and other parameters, the results of the graphics, the program has Chinese comment, convenient and easy to use)

使用usrp和gnuradio接收AM信号的代码，还有AM发送的信号以及说明的pdf(Receiving AM Signals from Data Files,python code,document)

本程序利用交替优化的方法实现了8-PSK信号在多普勒频移条件下的相位和定时双参数同步，不仅程序注释清晰，而且附上该程序实验报告，力求便于读者理解。(By optimizing alternately, this program realizes two parameters synchronization of phase and timing for 8-psk signal under Doppler frequency shifting channel. For better understanding of readers, I not only note the program clearly, but also provide the experimental report in the rar.)

说明：  载波同步仿真，使用的是反馈补偿法，接收信号经补偿矩阵，误差提取，环路滤波，相位累加器后反馈回补偿矩阵，稳定后估计相位趋近相位差，存在相位模糊情况。(the simulation of the carrier synchronization)

外辐射源雷达中直达波对消matlab程序，使用自适应滤波的算法(adaptive_filter algrithm)
