A Trade-Off Analysis Of Energy Detectors And Partitioned Search For Primary Detection, Robert H. Morelos-Zaragoza, Birsen Sirkeci, Vishal Sawant

Robert Henry Morelos-Zaragoza

Cognitive radios aim to coexist in the unused spectrum bands which are licensed to primary users without harming the primary transmission/reception. For a cognitive radio, it is important to detect the band in which the primary is operating as fast as possible and with high reliability in order to adapt its transmission. In this work, we propose P-partitioning method in combination with energy detectors for the search of the band that the primary user is operating.

Cognitive Radio: Fundamentals And Opportunities, Robert H. Morelos-Zaragoza

Robert Henry Morelos-Zaragoza

This talk is aimed at MSEE students in San Jose State University. It provides an overview of cognitive radio concepts and technologies. A MATLAB Simulink of demonstration of digital channel selection using a low IF radio architecture is presented. Technical challenges that remain to be solved in this area are identified.
