曲面拟合01

Multi-Carrier and Spread Spectrum Systems最新版本对OFDM wimax lte都有阐述(Multi-Carrier and Spread Spectrum Systems the latest version of the OFDM wimax lte has described)

program for finite impulse response fiter

本程序能实现任意阶的Zernike多项式的系数模拟和相位屏模拟。(This procedure can be of any order Zernike polynomial coefficient simulation and phase-screen simulation.)

基于PID控制，其仿真效果明显，能够达到预期的效果，希望以后能研究出更好的控制。(Based on PID control, the simulation results significantly, to achieve the desired results, I hope to be able to come up with better control.)

gabor是将图像转换成gabor特征，增强系统鲁棒性，使其不易受外界条件影响；norm是将图像的灰度值统一归一到一个范围内，便于同等使用图像。(gabor gabor is a feature to convert images to enhance the system robustness to make it less susceptible to external conditions affect norm is a uniform gray value image normalized 1-1 range, the same easy to use images.)

主要讲解的低噪比下跳频信号的调速估计问题，可以作为一定的参考(The main explanation of the low-noise ratio of the speed estimation of frequency hopping signals, can be used as a reference)

in this file is distribution-system

对信号进行Wigner-Ville分布分析的matlab函数(The matlab function of Wigner-Ville distribution analysis.)

用matlab编写程序计算3机9节点算例系统的潮流及三相短路电流。(The program is written in matlab to calculate the power flow and three-phase short-circuit current of the 3-machine 9-node example system.)

Low Density Parity Check code is a error control code used in the DVBS2 standard codec
