从2d图片中提取轮廓特征，通过线性回归，建立从特征到3d人体姿态的回归函数，来实现人体3d姿态评估(Contours extracted from the 2d image features, by linear regression, the establishment of 3d human body posture from the feature to the return of function, to achieve the body posture assessment 3d)

DBPSK调制模式在高斯信道下的误码率。(the ber performance of DBPSK through gaussian channel.)

很好的关于风机的资料,希望对大家有所帮组。(the material of Wind turbines )

自己编的微分方程求解的程序,没有调用matlab的函数(Own procedures for solving differential equations, there is no call matlab function)

均匀量化和非均匀量化在性能上存在着显著的差异，这种差异可以用信号通过量化器后的量躁比来反映出来。本程序用曲线表示了理论和实际两个方面下两种量化的量躁比。从而可观察他们的性能上的差别。(There are significant differences with the function between Uniform quantization and non-uniform quantization ,which can be quantified by SNR from the quantizer.This program use the curves to denote the SNR of theory and practical signal.Then we can observe the performance of the differences.)

mit bih file reader, and application of stft on mit bih source files, this is experimental and needs improvement but help yourself anyway.

说明：  这是基于MATLAB系统上开发的,应用于小波分析方面,很有用的程序模块,书名为"MATLAB在小波分析中的应用"(This is based on the MATLAB system development, application of wavelet analysis, very useful program modules, entitled )

说明：  FDA方向图的matlab仿真实现 是最简单的均匀线阵(FDA beampattern Is the simplest uniform linear array)

FIR滤波器中汉宁窗和布莱克曼窗幅频特性曲线和相频特性曲线对比(FIR filter Hanning window and Blackman window of amplitude-frequency curve and phase frequency response curve compared)
