Abstract

Advanced receivers are a key component of the 5th
Generation (5G) ultra-dense small cells concept given their capability
of efficiently dealing with the ever-increasing problem of
inter-cell interference. In this paper, we evaluate the potential of
interference suppression receivers in real network scenarios using
a software defined radio (SDR) testbed. The experimentation is
carried out in an indoor office and open hall scenarios. In particular,
we study to what extent the interference suppression receiver
is an alternative to traditional frequency reuse techniques. To this
end we evaluate the Interference Rejection Combining (IRC) and
Successive Interference Cancellation (SIC) receivers and different
rank adaptation approaches. Each node in our software defined
radio (SDR) testbed features a 22 MIMO transceiver built with
the USRP N200 hardware by Ettus Research. Our experimental
results confirm that interference suppression receivers can be a
valid alternative to frequency reuse, by achieving nearly the same
outage and higher peak throughput performance.
