Fluid antenna systems (FAS) are an emerging technology that promises a significant
diversity gain even in the smallest spaces. It consists of a freely moving antenna in a small …

In this paper, non-orthogonal multiple access (NOMA) is investigated as a viable solution to
address spectrum scarcity in unmanned aerial vehicle (UAV) communications. Specifically …

Selection combiner output (SCO) cumulative distribution functions (cdfs) of multivariate
equally-correlated and exponentially-correlated (ec) Rician, and other correlated fading …

Unmanned aerial vehicles (UAVs) are set to play a prominent role in next-generation
communications networks. However, the shortage of available spectrum to support UAV …

In this paper, the droplet size distributions of high-velocity airblast atomization were
analyzed. The spray measurement was performed by a Phase-Doppler anemometer at …

Non-orthogonal multiple access (NOMA) system can meet the demands of ultra-high data
rate, ultra-low latency, ultra-high reliability and massive connectivity of user devices (UE) …

In this paper we present a bivariate Rician shadowed fading model where the shadowing is
assumed to follow a Nakagami-m distribution. We derive exact expressions involving a …

This paper investigates the performances of multiuser downlink opportunistic beamforming
(OBF) systems in both Rayleigh and Rician fading channels with the limited feedback …

Weighted fractional Fourier transform encrypted chaotic direct sequence spread spectrum
(WFRFT-CD3S) signal is aperiodic and complex Gaussian distributed. The aperiodicity and …

In this paper, we present a novel analytical framework for the calculation of the level
crossing rate (LCR) and the average fade duration (AFD) of fading channels sampled at a …
