消噪滤波的程序。。。。。。。。。。.....(De-noising filter procedures. . . . . . . . . ......)

用Matlab以及c语言求语音序列的倒谱 这某段语音信号求FFT、取模、取log、IFFT得到倒谱，并画图。选取一段进行分析，分别对浊音和清音各自求倒谱。(Using Matlab, as well as for c language serial Cepstral voice that voice signal for a certain period of FFT, check mode, check log, IFFT been cepstrum, and drawing. Select a section of the analysis, respectively, and the voiceless to voiced their demand cepstrum.)

近程模式下的单脉冲信号产生，频谱图,模糊函数图,模糊度等高线图，自相关函数图和多普勒敏感度(Short-range mode of the single pulse signal generator, spectrum map, fuzzy function maps, contour map of ambiguity, since the correlation function maps and Doppler sensitivity)

MATLAB 值得一阅，不可错过啊！eyediagram做眼图！(MATLAB is worth reading, not to be missed ah! eyediagram make eye!)

说明：  wisper that is useful for all of the algorithms.
