In this paper, the line-of-sight (LOS) multiuser multi-input multi-output (MU-MIMO) system present in an office environment is considered. The major idea behind the proposed work is to demonstrate the effect of allocated user bandwidth on the performance of a bandlimited MU-MIMO system in an office environment. The hypothesis is proposed to estimate the average MU-MIMO bandwidth of an office environment. The computer simulation results for a 2 x 2 LOS MU-MIMO scenario show great improvement in the performance of the MU-MIMO system for optimal user bandwidth allocation. Finally, the presented measurement results attest the MU-MIMO system theoretical and simulation performance improvement predictions.
