Spatial interference suppression is investigated for MIMO
FDR networks, where all the major interferences, i.e., IRI,
SI and MUI, are efficiently suppressed via distributed
beamforming. With the aim to improve overall system
performance, an optimization problem for minimizing
the total transmit power is formulated, and two iterative
distributed beamforming algorithms are developed via the
judicious use of spatial degrees of freedom of MIMO FDR.
