A single transmission selection scheme for downlink distributed antenna system in multicell environment

摘要

In this paper, based on maximum signal-to-interference-plus-noise ratio criterion at the receiver, we propose a single transmission selection scheme for distributed antenna system and investigate the corresponding ergodic capacity together with outage probability in multicell environment. Assuming that the channels suffer from independent non-identical Nakagami-m fading with integer values of fading severity parameter m, we derive exact closed-form expressions for the ergodic capacity and outage probability. Monte-Carlo simulations are carried out to validate the theoretical analysis. Simulation results show that the ergodic capacity and outage probability of the proposed single transmission selection scheme outperform that of blanket transmission scheme.
