Composite Fading Models based on Inverse Gamma Shadowing: Theory and Validation [PDF]
IEEE Transactions on Wireless Communications, 2021 We introduce a general approach to characterize composite fading models based on inverse gamma (IG) shadowing. We first determine to what extent the IG distribution is an adequate choice for modeling shadow fading, by means of a comprehensive test with ...

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

Erratum: Spectrum Map Construction Based on Optimized Sensor Selection and Adaptive Kriging Model [PDF]
Radioengineering, 2023 In the published version of the paper, there is an error in Fig. 7. Figure 7 should be the results of different construction methods when "the standard deviation of shadow fading is 3 dB", but in the published version it is the result of different ...

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.
