Frequency-conversion

说明：  一些时反的例程和其他代码，mat文件是信道信息(The Mat file is the channel information. There are some examples of the Time Reverse and communication system.)

数字信号处理，非常好的电子教程,值得学习(digital singal process book,very good，worth studying)

双音多频 DTMF（Dual Tone Multi Frequency），双音多频，由高频群和低频群组成，高低频群各包含4个频率。(Dual-tone multi-frequency signaling (DTMF) is used for telecommunication signaling over analog telephone lines in the voice-frequency band between telephone handsets and other communications devices and the switching center. The version of DTMF that is used in push-button telephones for tone dialing is known as Touch-Tone. It was developed by Western Electric and first used by the Bell System in commerce, using that name as a registered trademark. DTMF is standardized by ITU-T Recommendation Q.23. It is also known in the UK as MF4.)

说明：  在MATLAB中用一群算法实现三维路径规划的代码，可以运行，自己修改地图数据即可达到自己的需求(Using a group of algorithms to realize three-dimensional path planning code in MATLAB, it can run and modify map data to meet its own needs.)

说明：  无线通信系统中经典的功率控制博弈论算法matlab实现。(The classical game theory algorithm of power control in wireless communication system is realized by MATLAB.)

说明：  改进的fcm聚类算法，通过网格划分初始聚类区间(Improved FCM clustering algorithm)

插值与拟合，解方程，数据分析，包含收发两个客户端程序，三相光伏逆变并网的仿真。( Interpolation and fitting, solution of equations, data analysis, Transceiver contains two client programs, Three-phase photovoltaic inverter and network simulation.)
