Antenna Selection Performance of Distributed Antenna Systems in Full-Duplex Indoor Base Station

Abstract

The work in this paper is trying to answer the question: In a full-duplex indoor base station with antenna selection, what are the benefits of using distributed antennas instead of co-located antennas? In other words, how much the use of distributed antennas would contribute in mitigating the self-interference in the full-duplex system. A ray-tracing tool is used to characterize the indoor multi-path channel environment. Subsequently, a baseband analysis is done to evaluate the performance of the full-duplex system. The distributed antenna system slightly outperforms the co-located system in the studied scenario.
