Title
A Cognitive Radio (Cr) System Employing A Dual-Stage Spectrum Sensing Technique: A Multi-Resolution Spectrum Sensing (Mrss) And A Temporal Signature Detection (Tsd) Technique
Abstract
Spectrum sensing technology is most vital to the implementation of a CR system using dynamic spectrum resource management. This paper suggested a CR system architecture with a wideband dual-stage spectrum sensing technique - a coarse and a fine spectrum sensing. Specifically, a coarse spectrum sensing technique adopted wavelet transforms in this architecture to provide a Multi-Resolution Spectrum Sensing (MRSS) feature. Analog implementation of the MRSS block offers wideband, low-power, and real-time operation. A fine spectrum sensing technique used the beneficial properties of auto-correlation in time domain - Temporal Signature Detection (TSD). This TSD technique enables identifying the unique signature feature of each specific signal type. Moreover, this feature detection technique in time domain realizes simple and fast spectrum-detection compared to spectral feature detection methods.
