This paper proposes a novel LQ-based generalized side-information cancellation (GSIC) precoder for multiuser multi-input multi-output (MU-MIMO) downlink systems with sum-rate performance enhancement. The proposed transceiver comprises the following stages. First, a unitary transform matrix designed through the LQ decomposition of the MU-MIMO channel is proposed for suppressing MU interference and...
A novel generalized side-information cancelling precoder is proposed for the multiuser MIMO downlink systems over MIMO broadcast fading channels. The proposed transceiver involves the following stages. First, the minimum mean square error (MMSE) based channel inversion (MMSE-CI) technique is utilized to suppress multiuser broadcast interference. Next, using the generalized side-information cancellation...
