An FFT method for generating bandlimited Gaussian noise variates
Norman C. Beaulieu, Christopher C. Tan · 2002
Digital communication system simulation may require the generation of correlated Gaussian noise samples. In cases where the noise is bandlimited, as for raised cosine Nyquist signaling, generation of the correlated random noise samples using conventional approaches may be difficult or problematic. It is verified that an FFT based method is well suited for generating bandlimited Gaussian noise variates.
