Joint Power and Rate Allocation in Cognitive Radio Multicast Networks for Outage Probability Minimization
Ding Xu, Qun Li · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2014
The problem of resource allocation to minimize the outage probability for the secondary user (SU) groups in a cognitive radio (CR) multicast network is investigated. We propose a joint power and rate allocation scheme that provides significant improvement over the conventional scheme in terms of outage probability.
