Performance of a Relay Antenna Selection Based Dynamic Spectrum Sharing Protocol with Opportunistic Selection of Users

Performance of a Relay Antenna Selection Based Dynamic Spectrum Sharing Protocol with... We consider a cellular scenario in which a base-station primary transmitter communicates to its primary receivers (PRs) using a set of multiple antenna relay stations (RS). One of several RS that is selected is assumed to employ antenna selection. The primary network allows one of its users to access the secondary network simultaneously in the same two phases (by using a selected RS) through dynamic spectrum sharing principles. Such a framework allows the cellular system to increase its frequency utilization. We derive expressions for the outage and ergodic rate performance of such spectrum sharing communication links. Systems performing spectrum sharing are assumed to have a peak power constraint and use peak interference control (to limit interference to the PR). For a fixed primary outage, it is demonstrated that increasing the number of users improves the performance at medium values of SNR, whereas increasing the number of RSs improves the performance at high SNRs. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Wireless Personal Communications Springer Journals
