A General Numerical Method for Computing the Probability of Outage
2009 IEEE Wireless Communications and Networking Conference, 2009The outage probability is a fundamental performance metric, which has been widely investigated in the literature. In this paper, we develop a general method to compute the outage given the moment generating function (MGF). When computing the outage using the MGF, integration along the standard Bromwich contour suffers from a loss of accuracy due to ...

Outage probability analysis of heterogeneous relay networks
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018The heterogeneous wireless network is considered to be a cornerstone of the system architectural design of the next cellular network generations such as the fifth generation (5G) to alleviate the imminent capacity crunch. With the heterogeneity of the 5G cellular network, it is inevitable to have different statistical channel models within the same ...

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 ...

Multicanonical Estimation of Outage Probabilities in MIMO Channels
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010Communication over Multiple-Input Multiple-Output (MIMO) fading channels is of much interest in the current telecommunication context. Estimation of very small outage probabilities in such channels is an important, yet time consuming task, owing to the lengthy run-time requirements of traditional Monte Carlo (MC) simulations.

On the Outage Probability Optimization in MISO Rician Channels
2009 IEEE International Conference on Wireless and Mobile Computing, Networking and Communications, 2009We address the optimization issue of the outage probability in Rician block fading channels with $N$ transmit antennas and $1$ receive antenna. It is already known that the eigenvectors of the covariance matrix of the transmit signal that minimizes the outage probability are the normalized mean vector of the Rician channel and $N-1$ orthonormal vectors

Tight Upper Bound on the Outage Probability of QSTBC
IEEE Communications Letters, 2006Recently, the statistical properties of the equivalent channel representation of a multiple-input-multiple output (MIMO) system employing rate one quasi-orthogonal space-time block codes (QSTBC) for n T=2n, nges2 transmit antennas was characterized. It was shown, that these QSTBC were capable of achieving a significant fraction of the outage mutual ...

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.

Outage Probability for Opportunistic Relaying on Multicell Environments
VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009Opportunistic relaying has been shown to be an effective and practical method for implementing the cooperative diversity. However, most of previous works have focused on single cell environments and ignored the effects of interference from neighboring cells.

On the Outage Probability in Amplify-and-Forward Relay Channels
2009 IEEE Wireless Communications and Networking Conference, 2009The overall relay channel from the source to the destination via relays has temporal properties quite different from any cellular channel. This work presents a study for time-dependent performance of relay channels for both fast-fading and log-normal shadow fading in terms of average outage duration, frequency of outage and probability of outage ...
