Low-Complexity Downlink User Selection for Massive MIMO Systems
Haijing Liu, Hui Gao, Shaoshi Yang +1
In this paper we propose a pair of low-complexity user selection schemes with zero-forcing precoding for multiuser massive MIMO downlink systems, in which the base station is equip…

A Novel Scheme for Downlink Opportunistic Interference Alignment
Haijing Liu, Hui Gao, Wei Long +1
In this paper we propose a downlink codebook-based opportunistic interference alignment (OIA) in a three-cell MIMO system. A codebook composed of multiple transmit vector sets is u…

Low-Complexity Transmission Mode Selection in MU-MIMO Systems
Haijing Liu, Hui Gao, Anzhong Hu +1
We propose a low-complexity transmission strategy in multi-user multiple-input multiple-output downlink systems. The adaptive strategy adjusts the precoding methods, denoted as the…
