How to add a Gaussian noise signal with zero-mean in a given data set?

[Prabhu_006]

I have a real-time velocity measurement data set in a excel (.xlsx) file. Now I want to add the Gaussian noise signal with zero- mean in this real-time data to create two set of pseudo measurements. Could you please tell me how to do this in the excel sheet?

Gaussian noise immunity, translation invariance, and other useful properties of higher order spectra are also used in obtaining robust (t,f) representations and in the feature-extraction stage after a representation. Higher-order spectra (HOS) are Fourier representations of cumulants or moments of a stationary random process. They are functions of more than one frequency. The bispectrum is a function of two frequencies and is the FT of the third-order cumulant, which is a function of two lag variables. Unlike the power spectrum (which is the second order spectrum), HOS retain phase information.
