A novel approach for cognitive radio sensing using wideband chirp signal

Sensing the radio environment is probably the most important and challenging aspect in cognitive radio systems. Traditional sensing techniques have proven shortcomings ranging from inaccuracy to implementation complexity. Chirp signal is a wideband signal with variety of applications in communication and signal processing. In this paper, we introduce a novel approach for sensing the radio spectrum using chirp signal. This method is showing potential to improve sensing in cognitive radio environment at tolerable level of complexity.
