In the present scenario, an energy efficiency has become a matter of prime importance for
wireless networks. To meet the demands of an increased capacity, an improved data rate …

Non-orthogonal multiple access (NOMA) has been shown in the literature to have a better
performance than OMA in terms of sum channel capacity; however, the capacity superiority …

In mobile communication, the signal that a base station received cannot be regarded as a
point source anymore because of the multipath propagation. A distributed source model is …

Intelligent transportation systems (ITSs) of industrial systems have played an important role
in Internet of things (IOT). The assistant calibration system (ACS) of vehicles is an emerging …

Direction-of-arrival (DOA) estimation plays a crucial role in array signal processing across
various domains, including radar, sonar, wireless communications, and seismic exploration …

In this article, a novel two-dimensional direction of arrival (2-D DOA) estimation method
using unfolded coprime L-shaped array is presented. First, the signal subspace is divided to …

Channel estimation in the presence of pilot contamination-induced inter-cell interference
(ICI) is a major challenge in large-scale multiple-input multiple-output (LS-MIMO) systems. In …

In health monitoring systems, the base station (BS) and the wearable sensors communicate
with each other to construct a virtual multiple input and multiple output (VMIMO) system. In …

Abstract Mobile Ad Hoc Networks (MANETs) are communication networks formed on the fly
by radio-equipped mobile nodes without relying on any fixed infrastructure. Flooding is the …

Abstract Multiput-Input, Multiple-Output (MIMO) systems have greatly improved data speed,
connection stability, and spectrum efficiency, revolutionizing wireless communication. In …
