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.

Normal approximations for fading channels [PDF]

open access: yes2018 52nd Annual Conference on Information Sciences and Systems (CISS), 2018
Capacity and outage capacity characterize the maximum coding rate at which reliable communication is feasible when there are no constraints on the packet length. Evaluated for fading channels, they are important performance benchmarks for wireless communication systems. However, the latency of a communication system is proportional to the length of the

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.

Wideband Fading Channels With Feedback [PDF]

open access: yesIEEE Transactions on Information Theory, 2010
The Rayleigh flat fading channel at low SNR is considered. With full channel state information (CSI) at the transmitter and receiver, its capacity is shown to be essentially SNR log(1SNR) nats/symbol, as SNR goes to zero. In fact, this rate can be achieved with a just one bit of CSI at the transmitter (per fading realization) and with no receiver CSI ...

The Streaming-DMT of Fading Channels [PDF]

open access: yesIEEE Transactions on Information Theory, 2014
We consider the sequential transmission of a stream of messages over a block-fading multi-input-multi-output (MIMO) channel. A new message arrives at the beginning of each coherence block, and the decoder is required to output each message sequentially, after a delay of $T$ coherence blocks.
