Face_test_luminance

本程序是根据3gpp中tdd协议中的下行导频码的结构构造的导频码捕获的程序，在该程序中针对导频码的结构独创性的提出了加功率窗法的捕获，比普通的方法效率搞 用matlab编的(This procedure is based on 3GPP TDD agreement in the downlink pilot code structure of the pilot code acquisition procedure, in the pilot program code for the structure of original proposed law plus power window capture, than the ordinary efficient method to engage with matlab series)

说明：  缨帽变换的简短小程序，在MATLAB7.11.0里环境下运行(Tasseled cap transformation of the short program, run under the environment MATLAB7.11.0)

基于Matlab GUI的图像的DCT，自由调节压缩率，计算峰值信噪比，并图形化对比还原图像(Matlab GUI for image-based DCT, freely adjust compression rates, the peak signal to noise ratio, and reduction of image contrast graphic)

这是一个简单的语音基音检测方法，通过对语音信号进行滤波、分帧、求自相关函数，可得到浊音的基音周期，从而实现基频检测。(This is a simple voice pitch detection, voice signals by filtering, sub-frame, find the autocorrelation function, voiced the pitch period available to achieve the fundamental frequency testing.)

介绍了GMSK的背景，基本原理，调制解调方式等内容（英文）(GMSK introduces the background, basic principles, modulation and demodulation, etc. (English))

说明：  与FOA-GM配套的11输入量的灰色神经网络算法(Grey Neural Network Algorithms with 11 Inputs Matched with FOA-GM)

gvf snake 范例程式,以matlab撰写(gvf snake sample program to write matlab)

实现多目标粒子群优化功能，重点是进化因子的选取！！(implementation of multi objective particle swarm optimization function, the key is to the evolutionary factor!!)

3. Setting of a suitable threshold value.Then apply wavelet de-noising and compression on wavelet coefficients and thresohlding using global positive threshold value. So that a compressed image can be transmitted in an efficient manner.

本程序用matlab仿真卫星及轨道，希望对大家的学习有所帮助(This procedure simulation using matlab and satellite orbit, and they hope to be helpful to study the U.S.)
