Abstract

In this paper, a multi-input multi-output (MIMO) full-duplex system is addressed, where both the transmitter and receiver have multiple antennas. Fundamental problems of the MIMO full-duplex technique are discussed, and possible solutions are presented. In particular, the transceiver designs that have been reported in the literature are technically reviewed, and their problems are discussed investigating the feasibility of the full-duplex technique in commercialized systems such as LTE and WiFi.

본 논문은 송수신기가 다중 안테나를 가지고 있는 multi-input multi-output (MIMO) 시스템에서 송수신을 동시에 수행하는 full-duplex 기법을 다룬다. MIMO full-duplex가 가지는 근본적인 문제에 대해 알아보고, 이를 위한 해결 방안에 대해 조사한다. 특히, 그동안 학계에서 논의 되고 있는 MIMO full-duplex 송수신기 설계 기법에 대해 기술적으로 리뷰하고 문제점들에 대해 고찰하고, LTE 및 WiFi 등의 상용화 시스템에서 사용 가능성에 대해 분석한다.
