HT_identification

using dbscan to clustering in matlab

说明：  通信大牛李叶关于ofdm信道估计的经典论文，研究此方向必看(Daniel Lee leaves on the communication channel estimation ofdm classic paper, research in this direction must see)

RGB和Lab颜色空间互相转换Matlab代码，亲测，非常好(Codes to transfer between RGB and Lab color space. Perform perfectly)

说明：  反投影算法，使用matlab编程，对图像进行高分辨率的重建算法(Back-projection algorithm using matlab programming, high-resolution image reconstruction algorithm)

蒙特卡洛，随机状态生成，模拟法抽样等 小程序不太好(Monte Carlo)

cdma系统matlab仿真程序，信道包括加性白高斯噪声，复合加性白高斯噪声，瑞利衰落，频率选择性瑞利衰落，双信道瑞利衰落。直扩调制，直扩解调。20段小程序，很不错。(cdma system matlab simulation program, channel, including AWGN, complex AWGN, Rayleigh fading, frequency selective Rayleigh fading, dual-channel Rayleigh fading. Direct Sequence Spread Spectrum modulation, demodulation DS. 20 small procedures, is pretty good.)

说明：  matlab下几个三角函数实现的对比 。(matlab implementation of the next several trigonometric functions compared)

说明：  time delay estimator

matlab画图的使用方法，简单的画一些图形。(matlab drawing to use a simple painting some of the graphics.)

matlab程序，混沌粒子群算法，混沌优化和粒子群优化两者的结合(Matlab program, chaotic particle swarm optimization)
