The κ − μ / Inverse Gamma Fading Model
Statistical distributions have been extensively used in modeling fading effects in conventional and modern wireless communications. In the present work, we propose a novel κ− μ composite shadowed fading model, which is based on the valid assumption that the mean signal power follows the inverse gamma distribution instead of the lognormal or commonly used gamma distributions. This distribution h...
متن کاملThe η − μ / Inverse Gamma Composite Fading Model Seong
In this paper we propose a new composite fading model which assumes that the mean signal power of an η−μ signal envelope follows an inverse gamma distribution. The inverse gamma distribution has a simple relationship with the gamma distribution and can be used to model shadowed fading due to its semi heavy-tailed characteristics. To demonstrate the utility of the new η−μ / inverse gamma composi...

متن کاملGamma Composite Fading Models: Fundamental Statistics and Empirical Validation
The κ-μ / inverse gamma and η-μ / inverse gamma composite fading models are presented and extensively investigated in this paper. We derive closed-form expressions for the fundamental statistics of the κ-μ / inverse gamma composite fading model, such as the probability density function (PDF), cumulative distribution function (CDF), moment generating function (MGF), higher order moments and amou...
متن کاملUnified Representation of κ − μ / Gamma , η − μ / Gamma , and α − μ / Gamma Fading Channels Using a Mixture Gamma Distribution with Applications to Energy Detection
In this letter, the performance of an energy detection (ED) is analysed over different composite generalized multipath/gamma fading channels, namely, κ−μ/gamma, η−μ/gamma, and α − μ/gamma. The mixture gamma (MG) distribution is employed to approximate with high accuracy the signal-to-noiseratio (SNR) for all these channels. General, mathematically tractable, and unified analytic expressions for...
