Optimal non‐outage probability maximising the outage rate in Rayleigh channel [PDF]
Electronics Letters, 2016 In this paper, we derive an analytic closed-form of the optimal non-outage probability value which maximizes the outage rate in a Rayleigh channel. Furthermore, asymptotic approximations of both the optimal non-outage probability and the maximum outage rate can be deduced from the proposed analysis.

IET Communications, Volume 17, Issue 2, Page 171-182, January 2023., 2023 Abstract In this article, robust beamforming (BF) and artificial noise (AN) design method is proposed for multiuser broadcast secure transmission under secrecy outage probability (SOP) constraints. A special scenario is assumed that the transmitter cannot obtain the accurate channel state information (CSI) of the users' channel, and different users ...

WiMAX on FSO: Outage Probability Analysis [PDF]
IEEE Transactions on Communications, 2012 The transmission of multiple wireless signals over optical links has attained a great research interest nowadays. In case where optical fibers are difficult to be deployed, or installation cost is prohibited, optical wireless systems provide an efficient alternative means.

Distributed remote antenna unit with selection‐based of (RoF‐IoT) paradigm: Performance improvement
IET Communications, EarlyView., 2022 Abstract Mixing the wireless medium with fiber optics can form a new communication system called a radio‐over‐fiber (RoF) network; it is a promising solution that can provide high bandwidth and a reliable connection between numerous sensors in wireless sensor networks (WSN) and the central office (base station) within a particular area.

Outage Probability Under Channel Distribution Uncertainty [PDF]
IEEE Transactions on Information Theory, 2011 Outage probability and capacity of a class of block fading MIMO channels are considered under partial channel distribution information. Specifically, the channel or its distribution is not known but the latter is known to belong to a class of distributions where each member is within a certain distance (uncertainty) from a nominal distribution ...

Performance evaluation of cognitive relay networks for end user mobile over mixed realistic channels
IET Communications, Volume 17, Issue 2, Page 228-245, January 2023., 2023 Abstract Cognitive relay network is a spectrum dynamic paradigm that exploits the unused portions of the licensed spectrum. This is based on merging both cooperative relaying techniques and cognitive radio network to achieve spectrum efficiency and enhance the overall system performance.

Precoding for coded communication on block fading channels and cooperative communications [PDF]
, 2011 We study precoding for the outage probability minimization of block fading (BF) channels and BF relay channels. Recently, an upper bound on the outage probability with precoding was established for BF channels, but only for high instantaneous SNR.

Optimum Power Randomization for the Minimization of Outage Probability [PDF]
IEEE Transactions on Wireless Communications, 2013 The optimum power randomization problem is studied to minimize outage probability in flat block-fading Gaussian channels under an average transmit power constraint and in the presence of channel distribution information at the transmitter. When the probability density function of the channel power gain is continuously differentiable with a finite ...

A hybrid approach for energy‐efficient routing in IoT using duty cycling and improved ant colony
IET Communications, EarlyView., 2022 The proposed approach poses the empirical notion to manage the energy consumption of the IoT network by considering the key performance indicators (KPI) like energy consumption, average residual energy, mobility factor, distance, throughput, and network lifespan to accomplish the tangible outputs.The proposed approach is modelled using DFD's and ...

Outage-Watch: Early Prediction of Outages using Extreme Event Regularizer [PDF]
, 2023 Cloud services are omnipresent and critical cloud service failure is a fact of life. In order to retain customers and prevent revenue loss, it is important to provide high reliability guarantees for these services. One way to do this is by predicting outages in advance, which can help in reducing the severity as well as time to recovery.
