While in the case of a single-antenna PU there is a one-to-one mapping between IT and achievable rate, this correspondence does not hold anymore when a multiple-input multiple-output (MIMO) system is considered. In such cases, the spatial distribution of the interference must be taken into account, since it strongly affects the PU performance. To this end, we derive a closed-form expression for the maximum IT that can be tolerated by identifying the worst-case interference covariance matrix, which results in a multilevel waterfilling problem.","lang":"eng"}],"date_created":"2023-01-30T11:51:48Z","publication":"Proc.\\ Asilomar Conf.\\ Signals Syst.\\ Computers","status":"public","author":[{"first_name":"Christian","last_name":"Lameiro","full_name":"Lameiro, Christian"},{"first_name":"Wolfgang","last_name":"Utschick","full_name":"Utschick, Wolfgang"},{"first_name":"Ignacio","last_name":"Santamaría","full_name":"Santamaría, Ignacio"}],"date_updated":"2023-01-30T12:00:33Z","title":"Interference-Temperature Limit for Cognitive Radio Networks with MIMO Primary Users","user_id":"43497","type":"conference"}
