초록

이최근, 3GPP (3rd Generation Partnership Project) 에서는 폭발적으로 증가하고 있는 모바일 데이터 트래픽을 수용하기 위하여 사이드홀 (Sidehaul) 시스템을 개발하고 이에 대한 연구가 활발히 진행되고 있다. 사이드홀 시스템은 낮은 PAPR (Peak to Average Power Ratio)을 위해 SC-FDMA (Single Carrier-Frequency Division Multiple Access)를 기반으로 한다. 또한 제한된 공간에서 안테나 배열을 사용함으로써 MIMO (Multiple Input Multiple Output) 전송이 가능하게 한다. 본 논문에서는 사이드홀 시스템에서 ULA (Uniform Linear Array), UCA (Uniform Circular Array) 및 UPA (Uniform Planar Array)에 대한 안테나 배열을 설계하고 성능을 분석한다. 또한, 이웃셀로 부터 간섭의 영향을 줄이기 위하여 새로운 하이브리드 수신기 FSC(Full Suppression Cancellation)를 제안한다. 제안한 수신기는 IRC (Interference Rejection Combining)와 SIC (Successive Interference Cancellation)를 결합하여 간섭을 억제 및 제거 할 수 있다.

Recently, 3rd Generation Partnership Project (3GPP) has developed sidehaul system to cope with the explosively increasing mobile data traffic. The sidehaul system is based on single carrier-frequency division multiple access (SC-FMDA) due to its low peak to average power ratio (PAPR). Also, antenna array is designed to support multiple input multiple output (MIMO) in a restricted space. In this paper, we design the antenna array about uniform linear array (ULA), uniform circular array (UCA) and uniform planar array (UPA), and analysis the performance in sidehaul system. In addition, we propose the novel hybrid receiver full suppression cancellation (FSC) to reduce the interference from neighbor cell in sidehaul system. The proposed receiver can suppress and cancel the interference by combining interference rejection combining (IRC) with successive interference cancellation (SIC).
