Abstract
This article presents a design and realization of tunable digital bandpass filter based on using biquadratic filter for spectrum sensing in cognitive radio. The biquadratic bandpass digital filter structure has shown and after that the tunable approach will be derived. The bandwidth and center frequency of the proposed tunable biquadratic digital bandpass filter can be tuned by tuning parameters. In each band, energy detection by spectrum sensing method will be used by cognitive radio users (CRU) for recognize the frequency spectrum of primary user (PU). If there are not having any PU in that band, the status of band will set to spectrum hole. Eventually, CRU can utilize this channel.
