Abstract—This paper investigates the zero-forcing (ZF) beamforming transmit strategy in the multiple-antenna multiuser downlink systems. We consider the case of mobile users equi...
The performance of a multiuser MIMO broadcast system depends highly on how the users being served are selected from the pool of users requesting service. Though dirty paper coding...
Abstract— For a multiple-input single-output (MISO) downlink channel with ¢ transmit antennas, it has been recently proved that zero-forcing beamforming (ZFBF) to a subset of (a...
— In this paper we compare the following two methods of transmit precoding for the multiple antenna broadcast channel: vector perturbation applied to channel inversion (also term...

Abstract— The capacity region of Gaussian Multi-InputMultiple-Output (MIMO) broadcast channels has been shown to be achieved by dirty paper coding (DPC). However, due to the high...
