基于广义矩阵分布的时频变换方法，用于信号时频分析。(Based on the Generalized time-frequency distribution matrix transformation method for time-frequency analysis.)

说明：  matlab的二维FDTD程序,PML边界(matlab two-dimensional FDTD program, PML boundary)

相当完整的NUFFT程序代码，注释非常清晰。简单易懂。国外网站上找到的程序，验证过完全正确。 (Fairly complete NUFFT code, comments, very clear. Easy to understand. Found on the website of the program abroad, proven entirely correct.)

This function is equivalent to matlab fft2 function, but without using for loops, instead this function is implemented using matrix multiplication.

基于matlab的QPSK实现，包含高斯信道和理想信道的调制、解调、星座图、功率谱以及误码率，有详细注释，很值得参考，绝对可以用(Based on matlab QPSK implementation, including gaussian channel and ideal channel modulation and demodulation, constellation diagram, power spectrum and the bit error rate, has detailed notes, is worth reference, can be used absolutely )

使用matlab软件进行的移相全桥仿真研究恒压（闭环）控制模式(Carried out using matlab software simulation of phase-shifted full-bridge constant voltage (closed loop) control mode)

说明：  自编粒子滤波算法程序，可解决非线性非高斯条件下的目标跟踪问题。(PF written by myself which provided solution of target tracking with non-linear and non-gauss environment.)
