又一个老外写的关于OFDM-Tutorial_Analysis文章，并附有程序，对学习OFDM仿真很有帮助(Written by another foreigner on the OFDM-Tutorial_Analysis article, together with the procedures of OFDM simulation study helpful)

MATLAB 曲线拟合小工具，适合初学者，高手直接无视之( MATLAB M file for curve fitting )

用matlab实现对矩阵的双三次插值算法实现(Bicubic interpolation matlab realize)

遗传算法计算多旅行商问题：多个商人从多个城市出发各自返回自己的出发城市。(MTSPF_GA Fixed Multiple Traveling Salesmen Problem (M-TSP) Genetic Algorithm (GA) Finds a (near) optimal solution to a variation of the M-TSP by setting up a GA to search for the shortest route (least distance needed for three salesmen to travel the start location to individual cities and back to the original starting place))

noma的固定算法和树形算法的matlab仿真，可以直接运行。(Matlab simulation of fixed algorithm and tree algorithm of noma can run directly.)

电力电子变换器采用重复控制策略。在反馈回路中设置一个内部模型，使该内部模型能够很好地描述系统外部信号特性，通过该模型的作用可使系统获得理想的指令跟踪特性，具有较强的扰动抑制能力。(Repetitive Control Strategy for Power Electronic Converter.An internal model is set up in the feedback loop, which can describe the external signal characteristics of the system well. Through the function of this model, the system can obtain ideal command tracking characteristics, and has strong disturbance rejection ability.)

用双线性变换法设计IIR数字滤波器 滤波就是将外界干扰的不需要的频率滤除掉，一面影响要测试数据的结果。比如如果是心电波的话，如果这是外界有很大的噪声干扰，滤波就是把不必要的信号给抑制掉，以便对心跳的正常测试。通过图比较，滤波后的明显比之前的要平滑，就是滤去干扰噪声的结果。采样间隔对实验有影响，取的过大会导致频率混叠。(Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.)

利用STFT可以估计信号在每片短时窗内的频率得到信号的瞬时频率，该曲线由一组时间和频率相对应的点组成，反映了信号频率随时间的变化。(Using STFT can estimate the frequency of the signal in every piece of short-time window get signal instantaneous frequency, the curve consists of a set of time and frequency of corresponding points, reflects the signal frequency changes over time. )
