宽带OFDM信号模型的建立，用于宽带OFDM信号的DOA估计，已经用于毕业设计(Wideband OFDM signal model, for broadband OFDM signal DOA estimation, has been used for graduation)

编写的基于LTE的SC_FDMA程序，其中包括调制、IFFT、子载波映射（分布式和集中式）、FFT及加CP。自己编写，可以运行。(LTE-based SC_FDMA written procedures, including modulation, IFFT, sub-carrier mapping (distributed and centralized), FFT, and plus CP. I have written, you can run.)

三相电压型SVPWM整流器，波形很好，抗干扰能力良好(Three phase voltage type SVPWM rectifier with good waveform and good anti-interference ability)

永磁同步电机直接转矩控制系统仿真模型，和大家交流学习(The permanent magnet synchronous motor direct torque control system simulation model, and we exchange learning )

说明：  利用商用WIFI和matlab对走、坐和蹲的三种数CSI 数据包进行预处理和特征提取(Commercial WIFI and matlab were used to preprocess and extract features of walking, sitting and squatting CSI packets)

基于PSIM的单极性和双极性全桥SPWM仿真，仿真结果正确，自己用过的(PSIM-based unipolar and bipolar full-bridge SPWM The simulation results are correct, used their own)
