Caching at the Edge: Outage Probability [PDF]
2021 IEEE Wireless Communications and Networking Conference (WCNC), 2021 Caching at the edge of wireless networks is a keytechnology to reduce traffic in the backhaul link. However, aconcentrated amount of requests during peak-periods may causethe outage of the system, meaning that the network is not ableto serve the whole set of demands.

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.

Outage Probability for MIMO MAC Channels [PDF]
Proceedings of the 1st International Conference on 5G for Ubiquitous Connectivity, 2014 In this paper, we investigate the outage probability for the mutual information of the sum rate for the MIMO (multiple input multiple output) MAC (multiple access channel) channel. We derive exact results for the “two users” case with two antennas and a general result for K users with an arbitrary number of antennas and different signal-to-noise ratios.

Proof of the Outage Probability Conjecture for MISO Channels [PDF]
IEEE Transactions on Information Theory, 2012 In Telatar 1999, it is conjectured that the covariance matrices minimizing the outage probability for MIMO channels with Gaussian fading are diagonal with either zeros or constant values on the diagonal. In the MISO setting, this is equivalent to conjecture that the Gaussian quadratic forms having largest tale probability correspond to such diagonal ...

Outage probability analysis of maritime FSO links
Frontiers in Communications and Networks, 2022 In this paper, the outage performance of the maritime free-space optical (FSO) communication system is analyzed, and a new maritime FSO link configuration is presented. The channel model for maritime FSO link includes the combined effect of turbulence, pointing error, angle-of-arrival (AOA) fluctuations, and attenuation.

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 ...

Optimal non‐outage probability maximising the outage rate in Rayleigh channel [PDF]
Electronics Letters, 2016 An analytic closed form of the optimal non‐outage probability value which maximises the outage rate in a Rayleigh channel is derived. Furthermore, asymptotic approximations of both the optimal non‐outage probability and the maximum outage rate can be deduced from the proposed analysis.

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 ...

Outage probability for soliton transmission [PDF]
Europhysics Letters (EPL), 2004 We study the interplay between amplifier noise and birefringent disorder in the case of strongly nonlinear (soliton) type of transmission in optical fibers. Assuming both noise and disorder to be weak, we evaluate the probability distribution function (PDF) of the Bit-Error-Rate (BER) for the values of BER that are much larger than the typical (average)
