| description | We
explore full-duplex technique in wireless communication particularly for relay
networks. We consider the relay to operate in full-duplex, which transmission
and reception are conducted in the same channel. We investigate potential
benefits of full-duplex technique in relay networks, which uses multiple
antennas for transmission and reception combined with Amplify-Forward (AF)
scenario. We study the effects of multiple antennas in terms of relay capacity.
We derive an ergodic capacity expression using Tracy-Widom distribution. Using
Singular Value Decomposition (SVD) and perfect Channel State Information (CSI),
we investigate three scenarios: First, we consider the relay to have antenna
larger than that of both source and destination. Second, we consider both relay
and destination to have antenna larger than that of source. Third, we consider
both relay and source to have antenna larger than that of destination. We show
the results that the capacity of relay with full-duplex technique is almost
twice the capacity of half-duplex. We show that increasing the number of destination
antennas is not help much when one of source antennas is small. Moreover, the
capacity decreases due to channel hardening effect, when the number of
destination antennas is larger than that of source. |
