SIMO communication with impulsive and dependent interference - the Copula receiver

Abstract : In this paper, we propose solutions for modelling dependence in impulsive noises. We use the copula framework that allows to represent the upper and lower tail dependencies that can not be captured by classical correlation (which, besides, is not adapted to α-stable distributions often considered in modelling impulsive noise). To illustrate the copula approach we consider a simple communication link with a single transmit antenna and two receive antennas and an adapted receiver architecture. We can derive the likelihood ratio that exhibits two components: one from the marginals and one from the copulas. We can then illustrate the impact of the dependence structure on the decision regions.
