Measurement of loop-back interference channels for outdoor-to-Indoor full-duplex radio relays
(2010) 4th European Conference on Antennas and Propagation (EuCAP), 2010- Abstract
- A full-duplex relay enhances the end-to-end spectral
efficiency compared to a half-duplex relay, provided that the
loop-back interference at relays is managed well. In order to
study the feasibility of the full-duplex relay, it is crucial to
measure and model the loop-back interference channels. This
paper presents a measurement campaign of these channels for
outdoor-to-indoor communications. A compact relay antenna
was developed to serve as a signal repeater between outdoor
base stations and indoor users, and was used for the loop-back
interference channel measurement. Measurement results revealed
that the mean interference level was -48 dB in the... (More) - A full-duplex relay enhances the end-to-end spectral

interference channel measurement. Measurement results revealed
that the mean interference level was -48 dB in the compact
relay antenna, and it could be further reduced by placing the
outdoor and indoor antennas in a different position referred to as
a separate relay. Combined with an appropriate countermeasure
to reduce the interference level, such as an interference canceller,
the full-duplex operation of indoor compact relay terminal was
found to be feasible. (Less)
