Miltiades C. Filippou, David Gesbert, George A. Ropokis · 2014
In this paper, an analytical performance study is carried out for cognitive radio (CR) systems with the intent of comparing the two most popular CR designs, namely the interweaved and underlay setups. The comparison is carried out on an equal footing, by measuring the achievable ergodic capacity
