Hot-spot wireless access exploiting shadowing diversity of distributed antennas

Abstract

In this paper, we investigate throughput improvement of hot-spot wireless access with distributed antennas. To exploit shadowing diversity of multiple distributed antennas, we propose an antenna selection, which takes both desired signal strength and interference strength into consideration. We also develop a power allocation approach to further enhance the throughput of wireless access. We then use wireless stadium as an example to demonstrate the effectiveness of the proposed approaches.This work may not be copied or reproduced in whole or in part for any commercial purpose.
