simulation modulate & demod FM

本程序对OFDM这一调制方式的基本流程进行了仿真，通过高斯白噪声信道，接收信号解调，对比发送和接收信号波形，并画出功率谱密度图形(This program OFDM modulation scheme of this basic flow of the simulation carried out by white Gaussian noise channel, the received signal demodulation, compare sent and received signal waveforms and power spectral density plot graphics)

Welch法：Welch法对Bartlett法进行了两方面的修正：一是选择适当的窗函数w(n)，并在周期图计算前直接加进去，加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时,可使各段之间有重叠，这样会使方差减小。(Welch method: Welch method of Bartlett method amendments in two respects: First, select the appropriate window function w (n), and in the cycle before CALPHAD directly incorporated, plus the advantage of the window, no matter what kind of window function can be so spectral estimation of non-negative. Second, when in subparagraph can overlap between paragraphs, this would reduce the variance.)

使用matlab编写的程序,关于目标动态跟踪的,里面有可测试的视频,可以稍微改动供自己用( the program was wrrited using matlab laguage)

orthogonal variable spreading factor (OVSF) is an implementation of Code division multiple access (CDMA) where before each signal is transmitted, the spectrum is spread through the use of a user s code. User s codes are carefully chosen to be mutually orthogonal to each other. These codes are derived from an OVSF code tree, and each user is given a different, unique code. An OVSF code tree is a complete binary tree that reflects the construction of Hadamard matrices.

光子晶体色散方程，matlab编译，程序简单易用，正确率高(Photonic crystal dispersion equation, matlab compiler, the program easy to use, the correct rate)

This circuit uses the AC6 block of SimPowerSystems™ library. It models a permanent magnet (PM) synchronous motor drive with a braking chopper for a 3HP motor. The PM synchronous motor is fed by a PWM voltage source inverter, which is built using a Universal Bridge Block. The speed control loop uses a PI regulator to produce the flux and torque references for the vector control block. The vector control block computes the three reference motor line currents corresponding to the flux and torque references and then feeds the motor with these currents using a three-phase current regulator.

一个eemd的程序，对于初学者非常的适用，程序只需要输入实验数据就可以调试出来，可以下下来看看(A eemd program for beginners, very applicable, can debug program only need to input experimental data, can be down and have a look)

单相基于PR控制的逆变器并网simulink搭建图，不错，很值得学习哦。(PR-based single-phase inverter control and network structures simulink diagram, yes, it is worth learning, oh.)
