Résumé :

Since the introduction of Opportunistic Spectrum Access as a new communication paradigm, research has focused on the introduction of improved techniques for spectrum sensing, establishing both theoretical foundations and building experimental prototypes proving the feasibility of spectrum sensing. None of the existing demonstrations however focused on the practical design constraints that have to be considered when using those techniques in low-power and low-cost hand held devices. The goal of this demo is to show the feasibility of spectrum sensing using reconfigurable analog and digital building blocks that have been designed to meet power, cost and area constraints of future opportunistic access devices that can access and sense a broad range of frequency bands. While the analog and digital building blocks have been designed for a broad range of sensing scenarios, focus in this demo will be on analog and digital multi-band sensing.
