Abstract

Software-defined Radios (SDRs) have developed exponentially in recent years. This is due to the high versatility that SDR platforms bring to communications systems. This survey aims to design, develop, and validate an SDR-based Cognitive Radio Sensing System with a very high functionality-to-cost ratio. A Radio Band Power Measurement System will be implemented, as a proof of concept, which will perform Energy Detector sensing involving apriori knowledge of the target signal characteristics. Thus, it will identify available 6, 7, and 8 MHz Digital Terrestrial Television (DTT) channels. The reliability and reconfigurability of the prototype reveal the added value that our approach brings to Spectrum Sensing.
