Blackamnn Tukey spectral estimation method

关于压扩算法对系统误码率影响的理论推导,一篇比较有用的文献，推导过程很详细(On the theoretical derivation of the bit error rate of the system influence the companding algorithm, a useful comparison of the literature, the derivation process is very detailed )

低通滤波器，对数据进行平滑，也叫做最小二乘法，Savitzky-Golay算法(a particular type of low-pass filter, well-adapted for data smoothing, and termed variously Savitzky-Golay, least-squares, or DISPO (Digital Smoothing Polynomial) filters. Rather than having their properties defined in the Fourier domain and then translated to the time domain, Savitzky-Golay filters derive directly from a particular formulation of the data smoothing problem in the time domain)

说明：  read an image then draw it s 3D Histogram,include R and G or R and B or G and B. I have never found correct code of this before

It contains the source code for the OFDM simulation in different types of fading environment and under different schemes ike bpsk, gmsk, msk, etc.Also it contains the transmitter design for the OFDM

经典的Harris角点检测程序，用matlab编的，可以参考(classic Harris corner detection procedures, using Matlab series, we can make reference to)

求解微分方程的解析解,这个工具可以代替R-K法等常用的数值求解方法。(the analysis solution of the differential equation)

主成分分析(Principal Component Analysis, 简称PCA)是一种常用的基于变量协方差矩阵对信息进行处理、压缩和抽提的有效方法。 (The principal component analysis (Principal Component Analysis, PCA) is a common covariance matrix of information processing, compression and extraction.)
