Abstract

This paper presents how to design fiber-optic relay node considering interferences between backhaul and access links. The way of proper arrangement of two different antennas is described as parameters of optical fiber length and radio frequency. Theoretical DUR due to the interference is provided relating to CNR performance mainly determined by the optical link. Provided that the radio frequency is 3.4 GHz and the antenna facing to eNB is positioned at high-SNR environments, optical fiber length (antenna separation) of 200 meters is enough to meet DUR of 30 dB. This will provide a solution of relaying without interference canceller for in-band relaying.
