In this paper, we develop a Stackelberg game with a non-uniform pricing in a two-tier
network environment, where multiple device-to-device (D2D) users reuse the uplink …

In this paper, we investigate a new radio resource allocation, three-dimensional (3D)
multiple input single output (MISO) beamforming and cross-tier interference mitigation in a …

Non-orthogonal multiple access (NOMA)-based device-to-device (D2D) network has
attracted widespread attention since it can address the problem of spectrum shortage in the …

As a promising new technology for green communication, backscatter communication has

This paper focuses on the robust beamforming design for downlink multi‐cell multiple‐input
multiple‐output (MIMO) nonorthogonal multiple access (NOMA) systems without having any …

In this paper, secure beamforming design in cooperative cognitive radio networks for
Internet of Things (IoT) is investigated, where we maximize the secrecy sum rate for the IoT …

This paper considers the problem of joint power allocation and antenna selection (J-PA-AS)
for downlink (DL) and uplink (UL) clustered non-orthogonal multiple-access (NOMA) …

In order to reduce the conservatism of the robust optimization method and the complexity of
the stochastic optimization method and to enhance the ability of power systems to deal with …

Cognitive radio (CR) is a candidate for opportunistic spectrum implementation in wireless
