The κ-μ distribution and the η-μ distribution
TLDR
In this paper, the authors proposed two general fading distributions, the kappa-mu distribution and the eta-mu distributions, for line-of-sight applications, for which fading models are proposed.Abstract:
This paper presents two general fading distributions, the kappa-mu distribution and the eta-mu distribution, for which fading models are proposed. These distributions are fully characterized in terms of measurable physical parameters. The kappa-mu distribution includes the Rice (Nakagami-n), the Nakagami-m, the Rayleigh, and the one-sided Gaussian distributions as special cases. The eta-mu distribution includes the Hoyt (Nakagami-q), the Nakagami-m, the Rayleigh, and the one-sided Gaussian distributions as special cases. Field measurement campaigns were used to validate these distributions. It was observed that their fit to experimental data outperformed that provided by the widely known fading distributions, such as the Rayleigh, Rice, and Nakagami-m. In particular, the kappa-mu distribution is better suited for line-of-sight applications, whereas the eta-mu distribution gives better results for non-line-of-sight applications.read more

A Mixture Gamma Distribution to Model the SNR of Wireless Channels
TL;DR: A mixture gamma (MG) distribution for the signal-to-noise ratio (SNR) of wireless channels is proposed, which is not only a more accurate model for composite fading, but is also a versatile approximation for any fading SNR.

Statistical Characterization of $\kappa{ - }\mu$ Shadowed Fading
TL;DR: It is shown that the sum and maximum distributions of independent but arbitrarily distributed κ - μ shadowed variates can be expressed in closed form and this set of new statistical results is finally applied to modeling and analysis of several wireless communication systems, e.g., the proposed distribution has applications to land mobile satellite (LMS) communications and underwater acoustic communications (UAC).

Fading Channel Issues in System Engineering
TL;DR: The character of multipath-induced propagational fading is reviewed, along with the interpretations underlying use of the Rayleigh fading model to describe the process statistics, and the system engineering problems of attempting to provide quantitative estimates of long-term link or network performance that takes into account the longer term channel variabilities.

The Probability Distribution of the Amplitude of a Constant Vector Plus a Rayleigh-Distributed Vector
TL;DR: In this article, the probability distribution of the instantaneous resultant amplitude of the sum of a constant vector and a Rayleigh-distributed vector is discussed. But the authors emphasize that two distributions are required to describe the Rayleigh distribution of a vector: the distribution of its amplitude and its phase, and that these distributions may be used to describe random variables occurring in ionospheric and irregular terrain propagation problems.
