一个无线定位算法仿真完整程序

说明：  matalb实现的协同过滤，里面包含很多重要算法，都已经实现(matalb achieve collaborative filtering, which contains many important algorithms have been realized)

是机器学习的例程，构成不同频率的调制信号，有详细的注释，在MATLAB中求图像纹理特征，包括调制，解调，信噪比计算，利用自然梯度算法，可实现对二维数据的聚类，有PMUSIC 校正前和校正后的比较。 ( Machine learning routines, Constituting the modulated signals of different frequencies, There are detailed notes, In the MATLAB image texture feature, Includes the modulation, demodulation, signal to noise ratio calculation, Use of natural gradient algorithm, Can realize the two-dimensional data clustering, A relatively before correction and after correction PMUSIC. )

说明：  信号的频域处理可分为经典方法和现代方法。经典方法以傅利叶变换为核心，只处理线性时不变问题。对非线性时变问题的处理是正在发展中的现代方法内容。经典的谱估计方法对采样得到序列进行处理隐含了一个加窗的操作，窗外的数据默认为零。所以可靠经典的谱估计方法在采样点数比较少的情况下，对频率的估计变得不可靠。现代谱估计方法以模型为基础，利用采样的数据建立模型，使谱估计的结果更能体现随机信号全局性的性质。(Heart sound analysis technology)

Wavelet based compression coding method. Allows the user to compress an image to upto 80 using wavelet based compression method.
