                                  ABSTRACT

In this talk, we present a blind interference alignment scheme for the
vector broadcast channel where the transmitter is equipped with M
antennas and there are K receivers, each equipped with a reconfigurable
antenna capable of switching among M preset modes. Without any
knowledge of the channel coefficient values at the transmitters and
with only mild assumptions on the channel coherence structure we show
that MK/(M+K-1) degrees of freedom are achievable. The key to the
blind interference alignment scheme is the ability of the receivers to
switch between reconfigurable antenna modes to create short term
channel fluctuation patterns that are exploited by the transmitter. In
addition, no channel knowledge at the receivers is required to null
the interference.
