Conventional optimization-driven secure relay selection relies on maximization algorithm and accurate channel state information (CSI) of both legitimate and eavesdropper channels …
In this paper, we study a class of minimum-energy scheduling problems in non-orthogonal multiple access (NOMA) systems. NOMA is adopted to enable efficient channel utilization …
Multiuser techniques play a central role in the fifth-generation (5G) and beyond 5G (B5G) wireless networks that exploit spatial diversity to serve multiple users simultaneously in the …
In practical content delivery, when the time-frequency resources are limited, it is a challenging task to satisfy terminals' data demand in a heavy-traffic and mutual-interfered …
We investigate the performance of multi-user multiple-antenna downlinks via joint antenna selection and power control design. In order to fully exploit the spatial diversity while …
A relay selection method is proposed for physical-layer security in multi-hop decode-and- forward (DF) relaying systems. In the proposed method, cooperative relays are selected to …

The joint spatial division and multiplexing (JSDM) is a two-phase precoding scheme for massive multiple-input-multiple-output (MIMO) system under frequency division duplex …
Through combined antenna selecting and power management design, we examine the effectiveness of multi-user multiple-antenna downlinks. A fraction of antennas are chosen to …
