详细的介绍了有关HMM模型的基本思想，是一本很好的资料！(Detailed introduction of the HMM model of the basic idea is a very good information!)

all matlab code are to the very hard and good is imporatnt

This code generate LFM chirp with any length, cycles, delays, and phase offsets. It also ensure continous phase change from one pulse to the other.

ofdm papr程序，适用于slm，pts等(ofdm papr procedures applicable to slm, pts, etc.)

说明：  DTMF的PDF说明文件，从原理到应用方法进行了详尽的叙述，使人理解双音多频的概念和使用方法(DTMF PDF Document from the application of the principle carried out a detailed narrative that people understand DTMF the concept and use)

说明：  提出了一种新的基于离散小波变换(DWT)与奇异值分解(SVD)相结合的数字图像水印算法。该算法将原始图像作小波分解并将小波分解得到的低频子带进行分块，对每一块进行奇异值分解后，选取每块中最大的奇异值通过量化的方法嵌入经过Arnold置乱后水印信息。(A new wavelet transform based on discrete (DWT) and Singular Value Decomposition (SVD) combination of digital image watermarking algorithm. The algorithm for wavelet decomposition of the original image and wavelet decomposition low-frequency sub-band are divided into blocks, each a singular value decomposition, the selection of each block by the largest singular value methods to quantify Arnold scrambled after embedding the watermark .)

常见的基于人类视觉特性的图像增强算法由于是同时完成动态范围压缩和对比度增强,导致增强图像的整体对比度不高、边缘部分效果不佳.通过分析人类视觉系统的全局和局部自适应调节原理及人眼视网膜神经节细胞感受野的传输特性,提出一种仿生图像增强法.为适应人类视觉系统对光强的主观感觉特性,对图像作全局亮度对数变换 并利用人眼的主观亮度感觉与实际光强的对数呈局部线性关系的特性,采用视网膜神经元感受野三高斯 模型来调整亮度图像的局部对比度 最后利用线性变换恢复图像的彩色信息.实验结果表明,该算法的增强效果良好,特别是对于图像边界处,既能很好地增强边缘对比,又可有效地提升区域亮度对比和亮度梯度信息.
