按键式电话如下图所示，当按下某一个键时会产生如图所示的相应的频率模拟信号，并通过对该信号频率的检测，识别出对应的按键。试通过编写一个数字信号分析程序，模拟完成上面的功能。(Touch-tone phone as shown below, when pressing a key will be generated as shown in the corresponding frequency analog signals and, through detection of the signal frequency to identify the corresponding button. Test through the preparation of a digital signal analysis program to simulate the function of the completion of the above.)

pso algorithm in matlab

A 2by3 MIMO model using Simulink. The decoder uses zero forcing algorithm. Set in the workspace the modulation order (QAM modulation), Doppler shift, SNR in dB, bit rate, sample per frame, max number of bits and max number of errors before running the simulation. Works also with BERTool but change the BER variable to ErrorVec. Included in the file a BER session with multiple runs and a figure for several runs.

初学雷达信号仿真的同学们可以好好看看。应该说是最基础 里面有MATLAB程序。写的比较好，对雷达发射信号有个很好的理解，以及和脉冲压缩的思想。同时也附有matlab程序。 内容提要： 雷达工作原理 线性调频（LFM）信号 LFM脉冲的匹配滤波 matlab仿真结果(Radar signal simulation of beginner students to have a look. Should say is the foundation which are MATLAB program. Write better, on the radar transmit signal to have a good understanding, and pulse compression of ideas. At the same time with MATLAB procedures.Abstract:The radar working principleLinear frequency modulated ( LFM ) signalLFM pulse matching filterMatlab simulation results)
