A broadcast channel that is very effective for disseminating common content becomes highly inefficient when the users request different content. To address this inefficiency of the broadcast channel over which a server ...

Cell-free massive multiple-input multiple-output (CF-mMIMO) systems, where multiple access points (APs) jointly and coherently serve a large number of user-equipments (UEs) in a geographical area, offer multi-fold improvement ...

Cognitive radio (CR) promises to significantly improve the utilization of scarce wireless spectrum. In the underlay mode of CR, which is the focus of the thesis, a secondary user (SU) can simultaneously transmit on the ...

With the advent of Massive multiple-input-multiple-output (MIMO) wireless communication systems, users can now enjoy high spectral efficiency and throughput leading to a better quality of service. The efficacy of these ...
