Probable outages of shielded transmission lines
Electrical Engineering, 1937Based on the observed phenomenon that flashover of transmission-line towers provided with 2 overhead ground wires occurs only when the product of tower footing resistance and tower surge current exceeds the insulation strength, the probable outages that will occur on a line can be obtained by a simple method.

Novel Outage Probability Based RWA Algorithm
OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference, 2008We propose a new algorithm for path selection and wavelength assignment in all-optical networks based on physical layer impairments and outage probability also including optional wavelength conversion.

Outage probability in FDMA/TDMA mobile communication networks
European Transactions on Telecommunications, 1994AbstractOne of the most crucial problems to solve in the field of mobile communication networks is the evaluation for a generic link of the network of the outage probability due to the random characteristics of the transmission system, essentially determined by anomalous propagation conditions, cochannel interference and user mobility.

Outage probability in digital cellular radio networks
[1992] Conference Record of the Twenty-Sixth Asilomar Conference on Signals, Systems & Computers, 1992The block outage probability that the voice segment is lost in digital cellular radio networks using TDMA because of a temporary fade during part of its reception is studied. The combined effects of multipath fading and shadowing of the wanted and interfering signals are considered. To this end, the model for RF outage probabilities, as appropriate for

Outage Probability of Rician Fading Relay Channels
MILCOM 2006, 2006In this paper, we consider the decode-and-forward (DF) relay network system over Rician fading channels. We derive an analytical expression for the outage probability of the highest achievable information rate of the system, which can be evaluated by employing standard numerical techniques. We also obtain some simple but tight lower and upper bounds on

Spatial Outage Probability Formula for CDMA Networks
2007 IEEE 66th Vehicular Technology Conference, 2007In this paper, we propose a new framework for the study of cellular networks called the fluid model and we derive from this model analytical formulas for interference, outage probability, and spatial outage probability. The key idea of the fluid model is to consider the discrete base stations (BS) entities as a continuum of transmitters which are ...

Improving Secrecy Outage Probability with Symbol Extension
2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014This paper reveals symbol extension is capable of improving secrecy performance in the multiple-input single-output (MISO) wiretap channel. We propose a symbol extension scheme jointly with the existing beamforming and artificial noise generation strategy to exploit the time variation of fading channel.

Modeling UpLink Power Control with Outage Probabilities
2007 IEEE 66th Vehicular Technology Conference, 2007We investigate models for uplink interference in wireless systems. Our models account for the effects of outage probabilities. Such an accounting requires a nonlinear, even nonconvex model, since increasing interference at the receiving base station increases both mobile transmit power and outage probability, and this results in a complex interaction ...

Outage probabilities in PMD compensated transmission systems
Proceedings 27th European Conference on Optical Communication (Cat. No.01TH8551), 2002We quantify the benefit of using some simple and relevant optical pre- and post-transmission PMD (polarization-mode dispersion) compensation techniques in terms of outage probability in optic transmission systems for both NRZ (non RZ) and RZ (return-to-zero) formats.
