Performance analysis of energy detection over hyper-Rayleigh fading channels
The 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
Entropy, 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]
Yugoslav 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 ...

Wideband Fading Channels With Feedback [PDF]
IEEE 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]
IEEE 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.

Sensors, 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 ...

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.

Analytical evaluation of adaptive-modulation-based opportunistic cognitive radio in Nakagami-m fading channels [PDF]
, 2012 The performance of adaptive modulation for cognitive radio with opportunistic access is analyzed by considering the effects of spectrum sensing, primary user (PU) traffic, and time delay for Nakagami- m fading channels.
