  • Abstract
    The concept of real-time spectrum sniffing - featuring a simple and low-cost circuit architecture with straightforward frequency scalability - is introduced for cognitive radio systems. A stepped group-delay phaser is proposed and demonstrated to eliminate the issue of frequency resolution limitation due to the dispersion spreading induced by conventional phasers.
