此程序是用于ofdm的调制的，采用QPSK的方法进行调制解调(This procedure is used for OFDM modulation, and the use of QPSK modulation and demodulation method)

kin Pixel Likelihoods and Skin Detection ----------------------------------------------- This Matlab code was developed for skin pixel detection in general imagery. Non-parametric histogram-based models were trained using manually annotated skin and non-skin pixels. A total of 14,985,845 skin pixels and 304,844,751 non-skin pixels were used.

本程序展示了小波分解， 重构，小波的高通滤波器，低通滤波器 的程序(This procedure demonstrated the wavelet decomposition, reconstruction, wavelet high-pass filter, low pass filter process)

软判决在OQPSK解调中实现对信号纠错的分析与应用(Soft-decision in OQPSK achieve signal demodulation analysis and application of error-correcting)

The ouput is the TE/TM band structure (first five bands) along pricipal directions (G-X-M-G) of a square-lattice photonic crystal with unit cell consisting of a substrate of "epb" relative permittivity with circular rods(holes) of "epa" relative permittivity and radius "r". Usage is SharifPWE_BZplot(N,RES,r,epa,epb) N: N in PWE algorithm (number at which the summations are truncated) RES: number of the divisions on every side of BZ#1 r: normalized radius of the circle of holes/rods (0<r<0.5) epa: relative permittivity of holes/rods epb: relative permittivity of the substrate Written by Amir Hosseini for the Course Photonic Crystals (C) Copyright 2005 School of Electrical Engineering Sharif University of Technology All Rights Reserved
