Performance analysis of energy detection over hyper-Rayleigh fading channels

open access: yesThe Journal of Engineering, 2015
This study investigates the performance of energy detection (ED)-based spectrum sensing over two-wave with diffused power (TWDP) fading channels, which have been found to provide accurate characterisation for a variety of fading conditions. A closed-form

Robust Automatic Modulation Classification Technique for Fading Channels via Deep Neural Network

open access: yesEntropy, 2017
In this paper, we propose a deep neural network (DNN)-based automatic modulation classification (AMC) for digital communications. While conventional AMC techniques perform well for additive white Gaussian noise (AWGN) channels, classification accuracy ...

Display probability of symbol errors for MQAM on Rician fading channel based on MGF method [PDF]

open access: yesYugoslav Journal of Operations Research, 2015
In this paper, we present a method to calculate the probability of error per symbol (Symbol Error Probability, SEP) of M-ary Quadrature Amplitude Modulation (MQAM) over a slow, flat, identically independently distributed Rician fading channels ...

Resource-Efficient Fusion over Fading and Non-Fading Reporting Channels for Cooperative Spectrum Sensing

open access: yesSensors, 2015
Recently, a novel resource-efficient technique for the reporting channel transmissions in cooperative spectrum sensing was proposed. In this technique, secondary users are allowed to simultaneously send their local decisions to the fusion center, saving ...

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

open access: yesIET 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.

Linear Equalization Combined with Multiple Symbol Decision Feedback Detection for Differential Space-Time Modulation

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
Differential space-time modulation (DSTM) for multiple antenna communication systems has been recently proposed for frequency-nonselective fading channels. In broadband multirate systems, frequency-selective fading may occur.

The Slashed‐Rayleigh Fading Channel Distribution

open access: yesMathematical 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 ...

General Switch-and-Stay Combing for Space Diversity over Rayleigh Fading Channels

open access: yesInternational Journal of Antennas and Propagation, 2012
Three multibranch switch-and-stay combining (MSSC) schemes are analyzed for Rayleigh fading channels, where different decision statistics for antenna switching (i.e., switch statistic) are used.

Selective fair scheduling over fading channels [PDF]

open access: yes2018 16th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt), 2018
Imposing fairness in resource allocation incurs a loss of system throughput, known as the Price of Fairness ($PoF$). In wireless scheduling, $PoF$ increases when serving users with very poor channel quality because the scheduler wastes resources trying to be fair.
