On the K and KG fading channels [PDF]
In this paper, the composite Rayleigh-Gamma and Nakagami-Gamma distributions are considered. Multipath short-term fading and long-term fading (shadowing) affect wireless channels.

Modeling Cellular Networks in Fading Environments with Dominant Specular Components [PDF]
Stochastic geometry (SG) has been widely accepted as a fundamental tool for modeling and analyzing cellular networks. However, the fading models used with SG analysis are mainly confined to the simplistic Rayleigh fading, which is extended to the ...

Unveiling the Hyper-Rayleigh Regime of the Fluctuating Two-Ray Fading Model
The recently proposed fluctuating two-ray (FTR) model is gaining momentum as a reference fading model in scenarios where two dominant specular waves are present.

The Slashed‐Rayleigh Fading Channel Distribution
We propose an alternative distribution for modelling fading‐shadowing wireless channels. This distribution presents certain advantages over the Rayleigh‐lognormal distribution and the K distribution and has proved useful in the setting described. We obtain closed‐form expressions for the average channel capacity and for the average bit error rate of ...

Shortest link scheduling in wireless networks under the Rayleigh fading model
Many shortest link scheduling algorithms adopt non-fading SINR interference model, which assumes that the received signal power will always remain determinate as long as the transmission power of the corresponding sender is fixed.

Bandwidth efficient QAM schemes for Rayleigh fading channels [PDF]
Techniques to improve the BER performance of 16-level QAM transmission over Rayleigh fading channels for PCM systems are presented, simulations were carried out with a carrier frequency of 1.9GHz, data rate of 64 kbit/s and mobile speed of 30mph. The residual BER was reduced by over an order of magnitutde, by introducing circular constellation coupled ...

On Block-Coded Modulation Using Unequal Error Protection Codes Over Rayleigh-Fading Channels [PDF]
This paper considers block-coded 8-phase-shift-keying (PSK) modulations for the unequal error protection (UEP) of information transmitted over Rayleigh-fading channels.
