本文主要讲的是图像变化中所使用的小波变换的一些基本知识(This article is primarily concerned with changing the image used in some of the basics of wavelet transform)

说明：  在极坐标下计算电力系统网络潮流以及加设FACTS（UPFC）原件后的潮流调整(Calculated in polar coordinates, and the trend of power system network to install FACTS (UPFC) original trend after adjustment)

本程序主要用来在设计广义切比雪夫滤波器时，根据给定的指标要求能综合处其所需要的耦合矩阵的耦合系数，从而方便进行下一步的设计(This procedure is mainly used in the design of generalized Chebyshev filter can be integrated Department, they need the coupling matrix of the coupling coefficient, according to the target set by the requirements, in order to facilitate the design of the next)

单径或多径瑞利衰落信道仿真，有较好的参考价值，主同步信号PSS在时域上的相关仿真，脉冲响应的相关分析算法并检验，基于kaiser窗的双谱线插值FFT谐波分析，重要参数的提取，结合PCA的尺度不变特征变换(SIFT)算法。( Single path or multipath Rayleigh fading channel simulation, There are good reference value, PSS primary synchronization signal in the time domain simulation related, Related impulse response analysis algorithm and inspection, Dual-line interpolation FFT harmonic analysis kaiser windows, Extract important parameters, Combined with PCA scale invariant feature transform (SIFT) algorithm.)

PSCAD，DC-AC-DC直流变压器，中间为100Hz高频变压器，一边实现Vf控制，另一边实现UdcQ控制。先在PSCAD中加载dqo_new_lib.psl后再加载DC_AC_DC_100Hz.psc。(PSCAD, DC-AC-DC DC transformer, the middle of 100Hz high-frequency transformer, while the realization of Vf control, the other side to achieve UdcQ control. First load dqo_new_lib.psl in PSCAD and then load DC_AC_DC_100Hz.psc.)

QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

C++Builder与Matlab7_1混合编程环境设置.(C++ Builder programming environment with mixed Matlab7_1 settings.)

PPT文件，关于matlab软件所有的工具箱的介绍和使用(it s a powerpoint of matlab on all toolboxes.)

说明：  使用灰狼算法优化的LSSVR程序，调试中(GWO optimized LSSVR program)

capon的程序，这几天写的，用用试试吧 (capon procedures written in the past few days, try to use with)
