Abstract [en]

We analyze the performance of bidirectionalcommunication links between two multi-antenna full-duplextransceivers, explicitly taking into account the effect of un-avoidable self-interference. The main theme of this paper is tocomparespatial-domainsuppression (implemented in the form of null-space projection) and subtractive time-domain cancellation: both schemes can eliminate the self-interference but the former consumes spatial degrees of freedom unlike the latter. We perform large-system analysis based on the replica method, while refer-ence simulations show that the asymptotic results are applicable also for practical systems with low number of antennas. Inparticular, we evaluate rate regions achieved by controllingthe spatial multiplexing order in each node and time sharingbetween different stream configurations. Consequently, we cancharacterize the rate loss of suppression versus cancellation.
