Joint Beamforming and Scheduling Design in Hierarchical Cognitive Radio Networks


Cognitive radio (CR) has been recently regarded as an important technique to improve spectrum utilization. In the thesis, we present a joint design approach to integrate power allocation, antenna beamforming and user scheduling to maximize the system sum rate of multiple users in the hierarchical CR networks with multicarrier transmissions. Concurrent… (More)
