Good practical guide to Matlab

给出了利用OFDM实现uwb的源代码及实例(Using OFDM to achieve given the source code and examples uwb)

设计一个低通数字滤波器，满足如下设计指标： 通带截止频率：0.2pi，通带波动：1dB 阻带截止频率：0.3pi，阻带衰减：15dB 要求：采用切比雪夫Ⅱ型滤波器原型，并分别采用脉冲响应不变变换法和双线性变换法进行设计，比较设计的结果，并进行分析 (Design a low pass digital filters that meet the following design specifications: passband cutoff frequency: 0.2pi, pass-band fluctuations: 1dB stopband cutoff frequency: 0.3pi, stop-band attenuation: 15dB requirements: use of Chebyshev filter prototypes with type Ⅱ and pulse response were the same transformation and bilinear transformation method designed to compare the results of the design and analysis)

说明：  基于密度的轨迹聚类，可以将轨迹进行分类，代码齐全，可供参考(Based on the density of trajectory clustering, trajectory can be classified, the code is complete, for reference)

matlab编写的m序列产生器以及通过simulink7.01仿真实现的两个模型，最后给出了相关系数的计算代码(m prepared matlab serial generator as well as through two simulink7.01 simulation model, the correlation coefficient is given for calculating the code)

该代码是对人脸进行光照处理，先进行gamma变换，然后进行Dog双边滤波，然后进行灰度亮度的均衡。该方法能够有效提高光照变化的情况下的系统识别性能(The code is the human face of light treatment, the first for gamma conversion, and then Dog bilateral filtering, then the brightness of the gray balance. The method can effectively improve the illumination changes in the case of system identification performance)

运用matlab对数字图像进行仿真，得到其压缩后的图像(Use of matlab for digital image simulation, the compressed image)
