Abstract

This paper presents the design and performance of fiber-optic relay node in which the antenna facing to the serving eNB and another antenna facing to UE are geographically separated via optical fiber. The way of proper arrangement of the two antennas is described considering interference between the backhaul and access links as parameters of optical fiber length and radio frequency. Theoretical CNR performance in the optical link and DUR performance due to the interference are described. Based on these results, the design examples for fiberoptic relay node are pointed out for system requirements. This strategy will play a role in realizing relaying in future mobile communication systems such as LTE-advanced and beyond.
