This paper paves the way when the assumption of normality is challenged within the wireless communications systems arena.Innovative results pertaining to the distributions of quadratic forms and their associated eigenvalue density functions for the complex elliptical family are derived, which includes il barone wine an original Rayleigh-type representation of channels.The presented analytical framework provides computationally convenient forms of these distributions.The results are applied to evaluate an important information-theoretic measure, namely channel capacity.

Superior performance in terms of higher capacity of the wireless channel is obtained when considering serra avatar price the underlying complex matrix variate t distribution compared to the usual complex matrix variate normal assumption.
