Abstract--In cognitive radio (CR) networks with multipleinput multiple-output (MIMO) links, secondary users (SUs) can exploit "spectrum holes" in the space domain to acce...
Abstract— Two driving goals for cognitive radio (CR) technique are maximizing spectrum utilization and avoiding interference to primary users. In this paper, we deal with the CR ...
