This dissertation by Erik Axell investigates spectrum sensing algorithms using second-order statistics to address detection challenges in cognitive radio networks. It explores methods for distinguishing noise from weak signals embedded in noise, crucial for minimizing interference in these systems. The work proposes detectors leveraging known signal covariance properties, applicable to various signal types, including OFDM and OSTBC signals. Theoretical frameworks and practical algorithms are introduced for spectrum sensing, emphasizing the importance of covariance matrix structures. Intended for researchers and engineers in wireless communications, the dissertation offers insights into optimizing cognitive radio performance through advanced detection techniques.
