In general, my research deals with signal processing techniques in wireless communication systems. This means mostly physical layer in addition to some MAC layer work. Research topics include in-band full-duplex, multiple antenna techniques, massive MIMO, compensation of RF non-idealities using digital signal signal processing, spectrum sharing, cooperative communications, optimization of network topologies, etc. The applied research methods are drawn from, communication theory, detection and estimation theory, stochastic geometry, random matrix theory, linear algebra, large system analysis...
