Outage Performance of Two-Hop OFDM Systems With Spatially Random Decode-and-Forward Relays [PDF]
IEEE Access, 2017 In this paper, we analyze the outage performance of different multicarrier relay selection schemes for two-hop orthogonal frequency-division multiplexing (OFDM) systems in a Poisson field of relays. In particular, special emphasis is placed on decode-and-

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.

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)

Outage Probability Analysis of THz Relaying Systems [PDF]
2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020 This paper focuses on quantifying the outage performance of terahertz (THz) relaying systems. In this direction, novel closed-form expressions for the outage probability of a dual-hop relaying system, in which both the source-relay and relay-destination links suffer from fading and stochastic beam misalignment, are extracted.

Outage Probability and Outage-Based Robust Beamforming for MIMO Interference Channels with Imperfect Channel State Information [PDF]
, 2012 In this paper, the outage probability and outage-based beam design for multiple-input multiple-output (MIMO) interference channels are considered. First, closed-form expressions for the outage probability in MIMO interference channels are derived under the assumption of Gaussian-distributed channel state information (CSI) error, and the asymptotic ...

Proof of the outage probability conjecture for MISO channels [PDF]
IEEE Transactions on Information Theory, 2011 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 ...

Precoding for Outage Probability Minimization on Block Fading Channels [PDF]
, 2012 The outage probability limit is a fundamental and achievable lower bound on the word error rate of coded communication systems affected by fading. This limit is mainly determined by two parameters: the diversity order and the coding gain.

Outage Probability in Arbitrarily-Shaped Finite Wireless Networks [PDF]
, 2013 This paper analyzes the outage performance in finite wireless networks. Unlike most prior works, which either assumed a specific network shape or considered a special location of the reference receiver, we propose two general frameworks for analytically ...

Fast Estimation of Outage Probabilities in MIMO Channels [PDF]
IEEE Transactions on Communications, 2004 Fast estimation methods for small outage probabilities of signaling in fading multiple-input multiple-output (MIMO) channels are developed. Communication over such channels is of much current interest, and quick and accurate methods for estimating outage capacities are needed.

Multicell Coordinated Beamforming with Rate Outage Constraint--Part I: Complexity Analysis [PDF]
, 2014 This paper studies the coordinated beamforming (CoBF) design in the multiple-input single-output interference channel, assuming only channel distribution information given a priori at the transmitters. The CoBF design is formulated as an optimization problem that maximizes a predefined system utility, e.g., the weighted sum rate or the weighted max-min-
