Maximum entropy investigation of the inter user interference distribution in a DS/SSMA system
The Maximum Entropy (MaxEnt) method is used to evaluate the Inter User Interference (IUI) probability density function in a Direct Sequence Spread Spectrum Multiple Access (DS/SSMA) system. This distribution is frequently assumed to be Gaussian distributed and is commonly known as the Gaussian Assumption (GA). By calculating the discrimination information (relative entropy) between the IUI-distribution, as inferred via the MaxEnt method, and a Gaussian distribution with equal second moments the Gaussian Assumption is quantified for the Nakagami-m faded channel. By altering the parameter m of the Nakagami-m distribution, the degree of fading can be varied and therefore the influence of fading on the Gaussian Assumption can be thoroughly investigated.
