Abstract :
This paper presents a brief overview of cognitive radio applications and discusses design challenges in implementing integrated circuits for spectrum sensing and wideband/reconfigurable transceivers. Our prototype chip of a cognitive radio receiver with multi-resolution, dynamic-range-scalable spectrum sensing capability over a wide frequency range of 30 MHz to 2.4 GHz is also described.
