dc.description.abstractIn this paper, we consider a cooperative opportunistic
beamforming scheme that can mitigate other cell interference
(OCI) in downlink cellular environments. By exploiting the
spatial channel correlation of adjacent cells, a random beam is
cooperatively generated to statistically avoid the OCI from
adjacent cells. Selecting its user for the proposed random beam
in an opportunistic manner, the proposed scheme can
simultaneously achieve both the multi-user diversity (MUD) gain
and OCI avoidance gain. Finally, the performance of the
proposed scheme is verified by computer simulation. The
simulation results show that the proposed scheme can noticeably
improve the spectral efficiency and the outage probability of
users near the cell boundary compared to conventional
opportunistic beamforming scheme.
