Clustering and Power Optimization for NOMA Multi-Objective Problems
Zijian Wang, Mylene Pischella, Luc Vandendorpe
This paper considers uplink multiple access (MA) transmissions, where the MA technique is adaptively selected between Non Orthogonal Multiple Access (NOMA) and Orthogonal Multiple…
Regularized Zero-Forcing for Multiantenna Broadcast Channels with User Selection
Zijian Wang, Wen Chen
A multiantenna multiuser broadcast channel with transmitter beamforming and user selection is considered. Different from the conventional works, we consider imperfect channel state…
Efficient Beamforming for MIMO Relaying Broadcast Channel with Imperfect Channel Estimation
Zijian Wang, Wen Chen, Jun Li
We consider a multiple-input multiple-output (MIMO) relaying boardcast channel in downlink cellular networks, where the base station and the relay stations are both equipped with m…
Capacity Performance of Relay Beamformings for MIMO Multi-Relay Networks with Imperfect R-D CSI at Relays
Zijian Wang, Wen Chen, Feifei Gao +1
In this paper, we consider a dual-hop Multiple Input Multiple Output (MIMO) wireless relay network in the presence of imperfect channel state information (CSI), in which a source-d…
Relay Beamforming Design with SIC Detection for MIMO Multi-Relay Networks with Imperfect CSI
Zijian Wang, Wen Chen
In this paper, we consider a dual-hop Multiple Input Multiple Output (MIMO) wireless multi-relay network, in which a source-destination pair both equipped with multiple antennas co…
Minimization of Sum Inverse Energy Efficiency for Multiple Base Station Systems
Zijian Wang, Luc Vandendorpe, Mateen Ashraf +2
A sum inverse energy efficiency (SIEE) minimization problem is solved. Compared with conventional sum energy efficiency (EE) maximization problems, minimizing SIEE achieves a bette…
