Beamforming design and performance analysis of a multicarrier MIMO cellular system with co-channel interference

Abstract EN

-This paper addresses the beamforming design for the base station (BS) and mobile stattion (MS) in multicarrier multiple-input multiple-output (MIMO) mobile cellular commmunication systems.

The transmit and receive beamformers at both the BS and MS are derived under co-channel interference (CCI) conditions in a Rayleigh fading environmment.

A closed-form expression for the maximum output signal-to-interference ratio (SIR) is achieved for interference-limited system.

The quadratic form included in the maximum output SIR is analyzed, and the probability density function (PDF) of its largeest eigenvalue is determined for Rayleigh-Rayleigh scenario (the BS and the co-channnel interferers are subject to Rayleigh fading).

Finally, the paper presents closed-form expressions for the PDF and the cumulative distribution function (CDF) of the output SIR and the system outage probability.
