A Nonbinary LDPC-Coded Probabilistic Shaping Scheme for a Rayleigh Fading Channel [PDF]

Entropy, 2022
In this paper, a novel, nonbinary (NB) LDPC-coded probabilistic shaping (PS) scheme for a Rayleigh fading channel is proposed. For the NB LDPC-coded PS scheme in Rayleigh fading channel, the rotation angle of 16 quadrature amplitude modulation (QAM ...

Rayleigh Fading Multi-Antenna Channels [PDF]

EURASIP Journal on Advances in Signal Processing, 2002
Information theoretic properties of flat fading channels with multiple antennas are investigated. Perfect channel knowledge at the receiver is assumed. Expressions for maximum information rates and outage probabilities are derived.

Sensing-Assisted Secure Communications over Correlated Rayleigh Fading Channels [PDF]

Entropy
We consider a secure integrated sensing and communication (ISAC) scenario, where a signal is transmitted through a state-dependent wiretap channel with one legitimate receiver with which the transmitter communicates and one honest-but-curious target that

Unveiling the Hyper-Rayleigh Regime of the Fluctuating Two-Ray Fading Model

IEEE Access, 2019
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.

Markov chain modelling of ordered Rayleigh fading channels in non‐orthogonal multiple access wireless networks

IET Signal Processing, 2023
A first‐order finite‐state Markov chain (FSMC) typically models the Rayleigh fading channel in the open literature because the first‐order FSMC is analytically tractable and can derive closed‐form results.

On the K and KG fading channels [PDF]

Serbian Journal of Electrical Engineering, 2009
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.

Discrete Rayleigh fading channel modeling [PDF]

Wireless Communications and Mobile Computing, 2004
AbstractIn order to understand the behaviour of upper‐layer protocols and to design or fine tune their parameters over wireless networks, it is common to assume that the underlying channel is a flat Rayleigh fading channel. Such channels are commonly modeled as finite state Markov chains.

The Slashed‐Rayleigh Fading Channel Distribution

Mathematical Problems in Engineering, 2019
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 ...
