Outage Performance of OSTBC in MIMO Channels with Shadowing

Wireless Personal Communications, 2007
In this letter, taking into account realistic propagation environments in the presence of log- normal shadowing, we analyze the outage performance of orthogonal space-time block coding (OSTBC) for an arbitrary finite number of transmit and receive antennas.

Outage Performance of Downlink IRS-Assisted NOMA Systems

GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020
In this paper, a downlink non-orthogonal multiple access (NOMA) system is studied, in which an intelligent reflecting surface (IRS) is deployed to enhance the coverage by assisting a cell-edge user device (UD) to communicate with the base station (BS).

Outage planning: human performance considerations

Conference Record for 1992 Fifth Conference on Human Factors and Power Plants, 1992
Human performance is an important factor in the assessment of outage plans and shutdown risk. An assessment process for examining plant outage working conditions against six fundamental methods for supporting reliable human performance is described. Results of a generic analysis using this process are presented.

Algorithm to improve the outage performance of IF Virtual MIMO system

2014 Australian Communications Theory Workshop (AusCTW), 2014
In this paper, we improve the outage performance of a 2 by 2 Virtual MIMO system based on Compute-and-Forward method [1]. The current scheme requires negotiations between the relays and destination to determine which decoded message the relay should transmit.

Outage performance analysis of relay selection in SWIPT systems

2016 IEEE Wireless Communications and Networking Conference, 2016
In this paper, we investigate the performance of relay selection for simultaneous wireless information and power transfer (SWIPT) systems. In particular, we consider a relay network consisting of both energy harvesting (EH) and non-EH relays. We further assume amplify-and-forward relaying and power-splitting at the EH units.

Outage Performance of OSTBC in Double Scattering MIMO Channels

Wireless Personal Communications, 2007
In this letter, taking into account realistic propagation environments in the presence of double scattering, we analyze the outage probability of orthogonal space-time block coding (OSTBC) for an arbitrary finite number of transmit and receive antennas.

Outage performance of FSO multi-hop parallel relaying

2012 20th Signal Processing and Communications Applications Conference (SIU), 2012
In this paper, we investigate the outage performance of relay-assisted free-space optical (FSO) networks which build upon the combinations of serial and parallel relaying. We assume log-normal atmospheric turbulence channels and derive outage probability expressions for multi-hop parallel relaying scheme under consideration.

Outage Performance of Cognitive Radio with Multiple Receive Antennas

IEICE Transactions on Communications, 2008
Outage performance of cognitive radios is analyzed in this paper. The scenario under consideration requires the cognitive radio to sense whether the primary user (PU) link is free (i. e. a spectrum hole exists) before making an active transmission using that link. Multiple antennas are available at the cognitive radio link to provide array gains at the

Outage Performance with Handover Triggering in Cellular Mobile Networks

Wireless Personal Communications, 2001
An approach to performance evaluation of cellular mobile networks is proposed, which includes the behavior of handover algorithms in the computation of outage probability. In a general system scenario, with a central cluster and interfering base stations, the average outage probability is computed along a trip of the mobile terminal that involves ...
