Abstract
Beamforming in multi-user MIMO (MU-MIMO) systems is
a vital part of modern wireless communication systems. Researchers
looking for best operational performance normally optimize the problem
and then solve for best weight solutions. The weight optimization
problem contains variables in numerator and dominator: this leads to
so-called variable coupling, making the problem hard to solve. Formulating
the optimization in terms of the signal to leakage and noise ratio
(SLNR) helps in decoupling the problem variables. In this paper we
study the performance of the SLNR with variable numbers of users and
handset antennas. The results show that there is an optimum and the capacity
curve is a concave over these two parameters. The performances
of two further variations of this method are also considered.
