Title:
Digital Gaussian noise simulator
Abstract:
A Gaussian noise is simulated by discrete analogue r.sub.i,j. A first parameter .alpha. and pluralities of first and second integers i and j are selected. A plurality of points i,j are identified and a magnitude s.sub.i,j is calculated for each point based on .alpha., i and j. The discrete analogue r.sub.i,j is based on a respective s.sub.i,j. Examples are given of .alpha. ##EQU00001## and D>i.gtoreq.0 and 2.sup.C>j.gtoreq.0, where B.gtoreq.0, 2.sup.B>A>0, C.gtoreq.1 and D.gtoreq.1, and magnitude .alpha..alpha..alpha..times..times..times..times..alpha..alpha. ##EQU00002## In some embodiments, a segment is defined based on .alpha. and i. The segment is divided into points based on respective values of j, and the magnitude is calculated for each point of the segment. The defining and dividing segments and calculating the magnitude is iteratively repeated for each value of i.
