Outage performance for amplify-and-forward channels with an unauthenticated relay [PDF]
2012 IEEE International Conference on Communications (ICC), 2012 We investigate a relay network where the source can potentially utilize an unauthenticated amplify-and-forward (AF) relay to augment its direct transmission of a confidential message to the destination. Since the relay is unauthenticated, it is desirable to protect the confidential data from it while simultaneously making use of it to increase the ...

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 ...

On the Feasibility of Wireless Energy Transfer Using Massive Antenna Arrays
, 2016 We illustrate potential benefits of using massive antenna arrays for wireless energy transfer (WET). Specifically, we analyze probability of outage in WET over fading channels when a base station (BS) with multiple antennas beamforms energy to a wireless

Outage Performance of Cooperative Systems Under IQ Imbalance
IEEE Transactions on Communications, 2014 In this contribution, we investigate the outage performance of OFDM-based Decode and Forward (DF), Amplify and Forward (AF) and Controlled DF (CDF) cooperative systems under IQ Imbalance (IQI). In particular, tractable and compact approximate outage probability expressions are derived and the effect of the different IQI parameters is analyzed for ...
