Multivariate generalized Gaussian density (MGGD)
is used to approximate the multiple access interference (MAI) and
additive white Gaussian noise in pulse-based ultrawide bandwidth
(UWB) system. The MGGD probability density function (pdf) is
shown to be a better approximation of a UWB system as compared
to multivariate Gaussian, multivariate Laplacian and multivariate
Gaussian-Laplacian mixture (GLM). The similarity between the
simulated and the approximated pdf is measured with the help
of modified Kullback-Leibler distance (KLD). It is also shown
that MGGD has the smallest KLD as compared to Gaussian,
Laplacian and GLM densities. A receiver based on the principles
of minimum bit error rate is designed for the MGGD pdf. As
the requirement is stringent, the adaptive implementation of the
receiver is also carried out in this paper. Training sequence of
the desired user is the only requirement when implementing the
detector adaptively.
