基于matlab的qpsk调制模块，可以调用随机数列进行调制，根据需要设置进制数(Qpsk modulation based on the matlab module, you can call out random numbers to carry out modulation, according to the need for M-ary number)

This is a simple position location algorithm using Least Square Estimation algorithm. Timing information is time of flight (TOA) of signal between Tx and Rx. This code generally describes the Positioning method, Also it plots final coordinate of node in 2D. All other information was inlcuded as comments in source code.

matlab实现Preisach模型，画出Everett函数以及Preisach平面(- approximate measured hysteresis loops - simulate arbitrary minor hysteresis loops - plot the Preisach function, the Everett function, the reversible component)

说明：  磁滞曲线的建立，基于MATLAB编辑器条件下，运用数学公式解方程的方法，求解微分方程(Establishment of hysteresis curve)

基于模态振型的固定结合面动态特性参数测试 (Based on a fixed mode shapes combined with dynamic characteristic parameters of the test surface)

菜单的仿真，通过修改菜单可以修改自己需要修改的参数，例如PID(Simulation menu, the menu can be modified by modifying the need to modify the parameters of their own, such as PID)

离散傅立叶变换已成为数字信号处理的重要工具，然而，它的计算量较大，运算时间长，在某种程度上却限制了它的使用范围。快速算法大大提高了运算速度，在某些应用场合已能作到实时处理，并且开始应用于控制系统。(Discrete Fourier Transform digital signal processing has become an important tool, however, the calculation of its larger, long computing time, but in a way limits the scope of its use. Fast Algorithm for greatly enhanced speed of operation, in some applications has been able to do real-time processing and control system began to be used.)

Denoising Reduces the total-variation of the image. Filters out noise while preserving edges. Textures and fine-scale details are also removed. In this demo the assumption is that a white Gaussian noise is added with a-priori known (or estimated) noise power (variance). The fidelity term to the input image is calculated automatically so that the power of the noise is reduced.
