Abstract
Simulation of noise and, more particularly, a coefficient generator for channel modeling, is described. A spectrum memory is for storing sets of constants for respective harmonics. At least one phase noise source is configured for generating phase noise. An Inverse Fourier Transform block is coupled to the spectrum memory and to the at least one phase noise source. The Inverse Fourier Transform block is configured to provide a read address to the spectrum memory for accessing at least one constant of a set of constants of the sets of constants from the spectrum memory and coupled to receive the phase noise from the at least one phase noise source.
