Description: 本程序利用奇异值分解对3通道彩色图像进行压缩分解，具体步骤如下：
压缩过程：
1. 选取子图像大小K值，把图像分解成M×M个子图像，IMG(s),s=1,2,…, M2，其中M=N/K，原始图像IMG大小为N×N。
2. 计算这M2个子图像的平均值average，对每幅子图像减去均值图像得到新图像。
3. 计算相关矩阵R，其元素定义为 。
4. 计算R的特征值与特征向量，计算每幅子图像与最大特征向量的内积，便得到编码，即压缩后的图像。
-This procedure using singular value decomposition of 3-channel color image compression decomposition, concrete steps are as follows: compression process: 1. Select the sub-image size K value, the image is decomposed into M × M sub-image, IMG (s), s = 1, 2, ..., M2, in which M = N/K, the original image IMG size N × N. 2. M2 calculate the average of sub-image average, for each sub-image minus the new images mean images. 3. Calculation of correlation matrix R, defined as its elements. 4. Calculation of the characteristics of R value and eigenvector calculated each sub-image with the largest eigenvector of the inner product, they will have to code, that is, the compressed images.

Description: The channel modeling work package WP1 of IST-WINNER project provided a Matlab implementation of
the WINNER Phase II Model (referred as WIM this onward). The main purpose of the WIM channel
models is to generate a radio channel realisations for a link and system level simulations. The
implementation is based on the earlier implementations of WINNER II interim model [6], WINNER I
(interim) model [3], 3GPP/3GPP2 Spatial Channel Model (SCM) [4] and SCM(E) Extension models. For
details concerning the WIM model, please refer to [1]. This document describes the SW implementation
structure of WIM, its input/output interface and its functionality. Channel model scenarios and parameters
are modified to correspond to IMT.EVAL [7] channel model.
