An Efficient Method for Evaluating Information Outage Probability and Ergodic Capacity of OSTBC System

Several numerical methods have been suggested in the past to compute the outage probability and the ergodic capacity of an orthogonal space-time block coding system. In this paper we add to this body of work by describing a simpler yet general method that relies on a more efficient Fixed-Talbot algorithm for numerical Laplace inversion. The framework developed can be applied to a wide range of fading distributions (including Rice, Nakagami-m, Nakagami-Hoyt and Weibull stochastic channel models) with unequal channel gains and also to independent and non-identically distributed (i.n.d) multiple input multiple output channels.
