Abstract :
In this paper, the impact of co-channel MIMO interference on MIMO Beamforming (MBF) in the desired link is investigated. The exact closed-form expression of the probability density function (pdf ) of the signal-to-interference ratio when the desired user has one antenna is derived. Due to the unavailability of the closed-form pdf expression for arbitrary (N,M) (where N and M are the number of transmit and receive antennas, respectively), a simple approximation for an arbitrary number of antennas is proposed and used to analyze the impact of various MIMO modes used by the co-channel base stations. Simulation results verify the validity of the analysis and the impact of cochannel MIMO modes on the desired MBF receiver is discussed.
