Network coding (NC) is a technique used for effective and secure communication by
improving the network capacity, throughput, efficiency, and robustness. In NC, data packets …

Many contemporary signal processing, machine learning and wireless communication
applications can be formulated as nonconvex nonsmooth optimization problems. Often there …

This paper studies the secure beamforming design in a multiple-antenna three-node system
where two source nodes exchange messages with the help of an untrusted relay node. The …

A framework for energy-efficient resource allocation in a single-user, amplify-and-forward
(AF), relay-assisted, multiple-input-multiple-output (MIMO) system is devised in this paper …

This paper considers joint linear processing at multi-antenna sources and one multiple-input
multiple-output (MIMO) relay station for both one-way and two-way relay-assisted wireless …

In sixth-generation (6G) communication networks, ultrahigh-data rate and reliability are
greatly vital for massive user connections and network sensors, such as Internet of Things …

In this paper, we investigate robust beamforming to improve the energy efficiency (EE) of
wireless networks when only imperfect or partial channel state information (CSI) is available …

Multiple antennas have played an essential role in spatial multiplexing and diversity
transmission for a wide range of communication applications. Most advances in the design …

A harvest-use-store power splitting (PS) relaying strategy with distributed beamforming is
proposed for wireless-powered multi-relay cooperative networks in this paper. Different from …

In this paper, we consider the performance of a two-way amplify-and-forward relaying
network (AF TWRN) in the presence of unequal power co-channel interferers (CCI) …
