它是关于矢量量化的语音识别，让看到他学者受益匪浅，日后定能拓展视野！(lovely and satisfactory)

对该题目的这篇论文进行了仿真，内容为对比MASSIVE MIMO和Small cell两种模式，比较了载波能量。(The topic of this paper simulation, content and Small cell contrast MASSIVE MIMO modes, compared carrier energy.)

Securing the IEEE 802.16 OFDM WiMAX PHYSICAL AND MAC Layer Using STBC Coding and Encryption

病态矩阵分析 多角度阐明什么是病态矩阵 并且采用了正交化的处理来解病态矩阵(Pathological matrix multi-angle matrix and to clarify what is ill treatment by the orthogonal matrix to solve ill)

第一个程序提取了图像灰度级为64的灰度共生矩阵，并计算了能量，熵，对比度，相关性，逆差矩这5个参数.第二个程序可以提取彩色图像的LBP纹理特征，可以提取采样点为8、16、24的统一模式（u2）、旋转不变模式（ri）、统一旋转不变模式（riu2）的LBP值。(The first program to extract a grayscale image GLCM 64, and calculate the energy, entropy, contrast, correlation, inverse difference moment these five parameters. The second program can extract LBP texture feature color images, sampling points can be extracted for 8,16,24 unified mode (u2), rotation invariant pattern (ri), unified rotation invariant pattern (riu2) of LBP values.)
