미래 통신 네트워크의 성능 향상을 약속하는 릴레이는 IMT-Advanced 시스템의 가장 유망한 기술 중 하나입니다. 본 논문에서는 실외 측정을 기반으로 한 다중 입력 다중 출력(MIMO) 릴레이 채널을 조사합니다. 기지국(BS)과 중계국(RS) 사이의 링크와 RS와 이동국(MS) 사이의 링크에 초점을 맞춘다. 먼저, IMT-Advanced 주파수 대역(2.35GHz, 50MHz 대역폭)에서 실시간 채널 사운더를 사용하여 채널을 측정했습니다. 그런 다음 공간 교대 일반 기대 알고리즘을 사용하여 다중 경로 구성 요소(MPC)의 매개 변수를 추출합니다. 두 링크의 MPC 매개변수를 통계적으로 분석하고 비교합니다. 양극화 및 공간 통계를 얻습니다. RS와 MS의 분리에 따른 전력 방위각 스펙트럼(PAS)과 교차 편파 판별(XPD)의 경향을 조사합니다. PAS를 기반으로 가시선 및 비시선 시나리오의 전파 메커니즘을 분석합니다. 또한, 채널 상관관계의 대략적인 폐쇄형 표현이 도출됩니다. PAS와 XPD가 채널 상관관계에 미치는 영향을 연구합니다. 마지막으로 BS, RS 및 MS의 안테나 구성에 대한 몇 가지 지침이 제시됩니다. 결과는 중계 채널의 다양한 특성을 드러내고 중계 시스템의 실제 배포를 위한 기초를 제공합니다.

Abstract: Relay, which promises to enhance the performance of future communication networks, is one of the most promising techniques for IMT-Advanced systems. In this paper, multiple-input multiple-output (MIMO) relay channels based on outdoor measurements are investigated. We focus on the link between the base station (BS) and the relay station (RS) as well as the link between the RS and the mobile station (MS). First of all, the channels were measured employing a real-time channel sounder in IMT-Advanced frequency band (2.35 GHz with 50 MHz bandwidth). Then, the parameters of multipath components (MPCs) are extracted utilizing space-alternating generalized expectation algorithm. MPC parameters of the two links are statistically analyzed and compared. The polarization and spatial statistics are gotten. The trends of power azimuth spectrum (PAS) and cross-polarization discrimination (XPD) with the separation between the RS and the MS are investigated. Based on the PAS, the propagation mechanisms of line-of-sight and non-line-of-sight scenarios are analyzed. Furthermore, an approximate closed-form expression of channel correlation is derived. The impacts of PAS and XPD on the channel correlation are studied. Finally, some guidelines for the antenna configurations of the BS, the RS and the MS are presented. The results reveal the different characteristics of relay channels and provide the basis for the practical deployment of relay systems.
