Abstract:Cognitive radio networks (CRN) are constantly in need for new technologies able to improve their performance. Hence, study of new spectrum sensing (SS) techniques and devices is extremely important for a development of more accurate and sensible devices. The Hadamard ratio-based spectrum sensor (HrS) is a robust method able to accurately sense the presence of a wireless signal by applying a statistic test based on maximumlikelihood (ML) of collected signal data. A further performance analysis of HrS techniques… Show more
