Resource optimisation using bandwidth-power product for multiple-input multiple-output orthogonal frequency-division multiplexing access system in cognitive radio networks

This study investigates resource allocation problems for a point-to-point multi-carrier multiple-input multiple-output cognitive radio network. Different from conventional resource optimisation problems, a joint power and bandwidth resource optimisation framework using the novel optimisation metric,...
