Optimal Power Allocation for MIMO-MAC in Cognitive Radio Networks

Optimal Power Allocation for MIMO-MAC in Cognitive Radio Networks

This paper considers a cognitive radio (CR) network, in which the unlicensed (secondary) users (SUs) are allowed to concurrently access the spectrum allocated to the licensed (primary) users, provided that the interference of SUs with the primary users (PUs) satisfies certain constraints. It is more...
