In this letter, we investigate the energy-efficient 3D placement of an unmanned aerial vehicle mounted base station (UAV-BS) that is capable of tilting its directional antenna. We attempt to find the optimal UAV-BS 3D location to support ground users

This paper presents a multi-mode transmission technique that can increase the T-R distance of UCA OAM systems. The proposed technique uses dual polarized UCA antennas to increase the number of simultaneously transmitable modes at a specific T- R dist

Taking the positions of pico-cell base stations (PBSs) into consideration, a scheme of cell range expansion (CRE) for maximum sum rate is addressed in heterogeneous multi-input multi-output multi-user wireless networks. The optimal CRE bias obtained

In this paper, we consider the multiple-input single-output (MISO) wiretap channel with a cooperative jammer (CJ). Motivated by the fact that corrupting pilot signals can effectively degrade the channel estimation at the eavesdropper (Eve), we emphas

In this paper, we tackle the physical-layer security issue in MISO wiretap channel considering the pilot-assisted channel estimation at the receiver side. Unlike the conventional schemes, we introduce the cooperative jamming scheme that transmits art

In this study, we investigated proton irradiation effects on resistive random access memory (ReRAM) comprising ZrOx/HfOx stacks. After irradiation, changes of current were observed in the initial state (IS). From the electrical conduction mechanism i
