Opportunistic spectrum sharing in relay-assisted cognitive systems with imperfect CSI
( IEEE , 2014 , Article)In this paper, we consider spectrum sharing between cognitive radio (CR) users and a licensed primary user (PU) to enhance the spectrum efficiency. In the considered scenario, the PU is not able to successfully transmit ... -
A predictive strategy for lifetime maximization in selective relay networks
( IEEE , 2009 , Conference Paper)Two algorithms based on an energy conserving dynamic transmit power threshold are proposed for improving the lifetime in relay networks utilizing selective relay strategies with amplify-and-forward (AF) relays. the lifetime ...
