The use of millimeter wave technologies offer a promising solution for dense small cell networks, despite having to contend with challenging propagation characteristics. In particular, user-induced effects can lead to significant channel variations d

In this paper, we extensively investigate the way in which κ-μ fading channels can be impacted by shadowing. Following from this, a family of shadowed κ-μ fading models are introduced and classified according to whether the underlying κ-μ fadin

A performance analysis of the effective capacity in two recently proposed generalized composite fading channels, namely $\kappa $ - $\mu $ /inverse gamma and $\eta $ - $\mu $ /inverse gamma composite fading channels, is conducted. To this end, accura

The F composite fading model was recently proposed as an accurate and tractable statistical model for the characterization of the composite fading conditions encountered in realistic wireless communication scenarios. In the present contribution, we c

This work investigates the secrecy capability of energy harvesting based overlay cognitive networks (EHOCNs). To this end, we assume that a message by a licensed transmitter is relayed by an unlicensed sender. Critically, the unlicensed sender uses e

Several RPT sensors have been developed to acquire objective and quantitative pulse waves. These sensors offer improved performance with respect to pressure calibration, size and sensor deployment, but not temperature. Since most pressure sensors are

In this letter, we derive exact closed-form expressions for the level crossing rate (LCR) and average fade duration (AFD) of the signal envelope in F composite fading channels. Using the novel expressions, we then investigate the behavior of the LCR
