The $\alpha$ - $\mu$ Distribution: A Physical Fading Model for the Stacy Distribution
TLDR
A fading model is introduced, which explores the nonlinearity of the propagation medium and derives the corresponding fading distribution-the alpha-mu distribution-which is in fact a rewritten form of the Stacy (generalized Gamma) distribution.Abstract:
This paper introduces a fading model, which explores the nonlinearity of the propagation medium. It derives the corresponding fading distribution-the alpha-mu distribution-which is in fact a rewritten form of the Stacy (generalized Gamma) distribution. This distribution includes several others such as Gamma (and its discrete versions Erlang and central Chi-squared), Nakagami-m (and its discrete version Chi), exponential, Weibull, one-sided Gaussian, and Rayleigh. Based on the fading model proposed here, higher order statistics are obtained in closed-form formulas. More specifically, level-crossing rate, average fade duration, and joint statistics (joint probability density function, general joint moments, and general correlation coefficient) of correlated alpha-mu variates are obtained, and they are directly related to the physical fading parametersread more

Low Power Wide Area Network Analysis: Can LoRa Scale?
Orestis Georgiou,Usman Raza +1 more
TL;DR: In this paper, the authors provide a stochastic geometry framework for modeling the performance of a single gateway LoRa network, a leading LPWA technology, and show that the coverage probability drops exponentially as the number of end-devices grows due to interfering signals using the same spreading sequence.

Residual Transceiver Hardware Impairments on Cooperative NOMA Networks
TL;DR: It is proved that the OP at high signal-to-noise ratios (SNRs) is a function of threshold, distortion noises, estimation errors and fading parameters, which results in 0 diversity order, and it is demonstrated that the outage performance of cooperative NOMA scenario exceeds the non-cooperative NomA scenario in the high SNR regime.

A Generalization of the Gamma Distribution
TL;DR: In this paper, a generalization of the gamma distribution is proposed, which is based on Liouville's extension to Dirichlet's integral formula, and the moment generating function is shown, and cumulative probabilities are related directly to the incomplete gamma function.
