代码说明:

  计算正弦信号加噪声的相关函数。系数b 决定余弦相关函数在噪声指数型相关函数中的“比重”。T为正弦信号周期。正弦信号加相关噪声的相关函数图像为一个指数函数和一个余弦函数叠加的波形。(Calculated sinusoidal signal plus noise correlation function. Coefficient b determine the cosine correlation function in the noise correlation function of exponential type in " proportion." T for the sinusoidal signal cycle. Sinusoidal signal plus noise correlation function related to the image as an index function and a cosine function superimposed waveform.)
