Abstract

This article investigates the scheduling of secondary users in a spectrum-sharing cognitive environment under the primary user’s outage probability constraint. A switched-diversity combining approach to schedule the secondary users is explored. Specifically, switch-and-examine, switch-and-stay, selection-combining, and post-selection scheduling algorithms are investigated. Secondary users’ average performance measures are derived for the scheduling algorithms and compared against those of a single-user cognitive system. Results of this work illustrate the trade-off between the complexity of a scheduling algorithm and its average performance.
