We study the problem of beamforming design for a Cognitive Radio (CR) system in which a multiple-input multiple-output (MIMO) link, identified as secondary link, wants to opportunistically communicate without harming a licensed MIMO system, called primary. In the proposed solution the opportunistic user designs its beamformer in order to span...

Cognitive radio, which enables smart use of wireless resources, is a key ingredient to achieve high spectral efficiency. LTE, the latest evolution of cellular standards, is widely adopted and also targets high spectral efficiency. Hence, to enable wide adoption of cognitive radio, using LTE as the physical layer is a natural choice. Targeting a...
