风力发电系统的不控整流+buck/boost电路控制模型(mdl of wecs using uncontrolled rectifier and buck/boost cuicits)

一个雷达回波模拟的matlab程序包,含有在RCS服从卡方分布,瑞利分布,对数正态分布下目标的的雷达散射截面模拟子程序， 具有径向加速度,径向速度,径向距离的雷达回波模拟,有3-D图形显示.(A radar echo matlab simulation package, containing the RCS subject to chi-square distribution, Rayleigh distribution, lognormal distribution of the target radar cross section simulation subprogram, with the radial acceleration, radial velocity, radial distance the radar echo simulation, there are 3-D graphical display.)

This MATLAB implementation computes a correspondence between two shapes based on ant colony optimization (ACO). The input shapes can be either two 2D contours (open or closed) or two arbitrary sets of 2D points. The algorithm is described in detail in:

OFDM系统仿真，包含了发射、信道估计、接受等完整的OFDM系统仿真(his simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. See settings.m for more details. )

说明：  对仿真的非平稳信号进行Hilbert-Huang变换，分析信号的时频特征。(The simulation of non-stationary signals, Hilbert-Huang transform analysis of time-frequency characteristics.)

基阵信号处理的图形设计有平面设计，球面设计以及线列设计(Base array signal processing)

线性预测LSM预测器，可以完成对信号的预测功能(adaptive linear prediction)

谱分析的改进程序，适用于初学者，也是刚刚开始学的，水平不是很高(Spectral analysis of the improvement program for beginners, is just beginning to learn, is not very high level of)

光于X射线衍射成像的过采样理论，可为数值模拟提供参考。(Oversampling theory of light in X-ray diffraction imaging, can provide a reference for numerical simulation.)

用MATLAB实验了仿真，目标存在抖动的情况。(Simulation experiments using MATLAB, there is jitter target situation.)
