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 ...

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.

Energy-Efficient Index Modulation With In-Phase/Quadrature Format in the Generalized Fading Channel
IEEE Access, 2021 Dual-mode (DM) or multi-mode (MM) index modulation (IM) techniques with the in-phase/quadrature (IQ) format have been investigated for improving the performance of the orthogonal frequency division multiplexing with IM (OFDM-IM) system in the frequency ...

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.

MLSE receiver for the dispersive Rayleigh fading channel [PDF]
Proceedings of ICC'97 - International Conference on Communications, 2002 A maximum likelihood sequence estimator for the dispersive Rayleigh fading channel is developed. Following [1, 2], the MLSE uses a Kalman based channel estimator to acquire the channel parameters necessary to formulate the maximum likelihood metric. However, unlike the MLSE receiver presented in [1, 2], the proposed receiver uses the f-power series ...

Adaptive modulation in a slow Rayleigh fading channel [PDF]
Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002 A novel, uneven protection phase shift keying technique is proposed for the encoding of the required modulation scheme in an adaptive modem arrangement, which exhibits an improved performance in comparison to previously proposed schemes. The performance is derived numerically and a system dependent optimisation is presented.

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 ...
