代码说明:

假定确定性函数 Y 具有加性高斯噪声,EVAR(Y) 返回这种噪声估计的方的差。 薄板样条平滑模型用来平滑 Y。它假设其广义的交叉验证分数是最小的模型可以提供的加性噪声方差。几个测试表明 EVAR 工作得很好"不太不规则"功能。

  • impulse
    ----------------------------------------------------- This file produces the output file test_impulse.wav containing an approximation to the unit impulse (delta) function. The value of alpha on [0,1] determines the bandlimit of the approximation. This method is used to avoid the technical difficulties in producing (and reproducing) an ideal impulse (delta) function in audio. This file also produces the .wav audio file test_audio.wav which is an audio test vector intended to be used in the impulse response inversion experiment. (4/24/2002) NOTE: Impulse is bandlimited to alpha*Fmax where Fmax = Fs/2, or the Nyquist frequency.
