Title: | Impact of outdated channel estimates on a distributed link-selection scheme for AF relaying networks |
Author: | Osorio, Diana Pamela Moya Olivo, Edgar Eduardo Benitez Costa, Daniel Benevides da Santos Filho, Jose Candido Silveira |
Abstract: | We investigate the impact of outdated channel estimates on the outage performance of a distributed link-selection scheme recently proposed for variable-gain amplify-and-forward relaying networks. In this scheme, either the direct link or the relaying link is preselected before each transmission, based on a distributed mechanism. We begin by showing that an exact analysis is rather intricate, yielding a multifold integral-form solution. Motivated by this, we then derive a simple closed-form lower bound, which, importantly, proves to be a very tight approximation to the exact outage probability. We also assess the system diversity order via asymptotic analysis |
