This paper considers spectrum sharing for wireless communication between a cognitive radio (CR) link and a primary radio (PR) link. It is assumed that the CR protects the PR transmission by applying the so-called ldquointerference-temperaturerdquo constraint, whereby the CR is allowed to transmit re...
