On Shadowing the κ-μ Fading Model [PDF]
IEEE Access, 2020 في هذه الورقة، نقوم بالتحقيق على نطاق واسع في الطريقة التي يمكن أن تتأثر بها قنوات التلاشي $\kappa $ - $\mu $ بالتظليل. بعد ذلك، يتم تقديم عائلة من نماذج التلاشي $\kappa $-$\ mu $ المظللة وتصنيفها وفقًا لما إذا كان التلاشي $\kappa $-$\ mu $ الأساسي يخضع لتظليل فردي أو مزدوج. في المجموع، نناقش ثلاثة أنواع من نموذج $\kappa $ المظلل الفردي -

Bivariate Rician Shadowed Fading Model [PDF]
IEEE Transactions on Vehicular Technology, 2018 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 single integral for both the joint probability density function (PDF) and the joint cumulative distribution function (CDF) and we also derive an exact closed-form expression for ...

The $\kappa$- $\mu$ Shadowed Fading Model With Integer Fading Parameters [PDF]
IEEE Transactions on Vehicular Technology, 2017 We show that the popular and general κ-μ shad- owed fading model with integer fading parameters μ and m can be represented as a mixture of squared Nakagami (or Gamma) distributions. Thus, its PDF and CDF can be expressed in closed-form in terms of a finite number of elementary functions (powers and exponentials). The main implications arising from such

Data-Aided Fading Estimation Technique for Shadowed Mobile Satellite Fading Channels [PDF]
Wireless Personal Communications, 2002 A novel data-aided fading estimation technique that employs both pilot and data symbols is proposed to significantly reduce the bandwidth redundancy of the pilot-symbol-aided (PSA) systems using receivers with low complexity and latency in the shadowed mobile satellite fading channels.

Double Shadowing the Rician Fading Model [PDF]
IEEE Wireless Communications Letters, 2019 In this letter, we consider a Rician fading envelope which is impacted by dual shadowing processes. We conveniently refer to this as the double shadowed Rician fading model which can appear in two different formats, each underpinned by a different physical signal reception model.

Efficient modeling of correlated shadow fading in dense wireless multi-hop networks [PDF]
, 2014 Correlated shadow fading has a detrimental effect on the performance of wireless systems. Neglecting shadowing correlations could lead to inaccurate simulation results and unreliable wireless system design.
