Abstract:
This paper studies the ergodic capacity for ubiquitous cooperative networks employing amplify-and-forward relaying in Rayleigh fading. A general asymmetric channel model is considered, in which the average signal-to-noise ratios associated with different wireless channels are generally unequal. We derive an exact expression of the ergodic capacity in a single-integral form, which serves as a benchmark for ubiquitous cooperative networks. To the best of our knowledge, this exact expression has not been reported in the literature. To evaluate this integral more efficiently, we develop a hybrid Gaussian quadrature expression in closed-form, which has a high relative accuracy. Finally, it is demonstrated that the obtained analytical results overlap the simulation curves, while the existing bounds are loose in various scenarios.
