Efficient Computation of Information Outage Probability and Ergodic Capacity of OSTBC System

Outage probability and ergodic capacity are important performance measures of communication systems over fading channels. Point-to-point communication systems are known to achieve tremendous improvements in channel capacity when MIMO schemes are applied. In this paper we investigate an efficient Fixed-Talbot algorithm for numerical Laplace inversion and apply it to evaluate the outage probability and ergodic capacity of OSTBC system. 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) MIMO channels.
