Abstract

A method for calculating channel capacity for M-ary digital modulation signal sets over an Additive White Gaussian Noise (AWGN) channel is presented. By representing the signal set and noise process as vectors in an N-dimensional signal space, the computation of channel capacity becomes a problem of integration in N dimensions. An attempt to approximate multiple integration is based on Cartesian products of Gauss-Hermite quadrature formulae. This approach allows channel capacity calculation at any value of signal to noise ratio (SNR). The required computing time is small for a small to moderate number of signals and number of dimensions
