ABSTRACT:
A Gaussian noise is simulated by discrete analogue ri,j. A first parameter α and pluralities of first and second integers i and j are selected. A plurality of points i,j are identified and a magnitude si,jis calculated for each point based on α, i and j. The discrete analogue ri,jis based on a respective si,j. Examples are given ofα=2B-A2Band D>i≧0 and 2c>j≧0, where B≧0, 2B>A>0, C≧1 and D≧1, and magnitudesi,j=1-αi+αi·1-α2C·j⁢⁢or⁢⁢sD-1,j=1-αD-1+αD-1·12C·j.In some embodiments, a segment is defined based on α 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.
