Reconfigurability with extremely low hardware complexity is the demanding requirement of today’s 5G world. The use of Farrow structure-based design of variable bandwidth (VBW) filters can effectively realize tunability in the filter structure with minimum hardware overhead. Low-complexity VBW filters play a vital role in applications such as spectrum hole detection, where reconfigurability is to be ensured with minimum delay, along with minimum power and area utilization. This paper proposes a novel reconfigurable filter structure based on Farrow filters and frequency translation, for effective detection of spectrum holes of any arbitrary bandwidth, available within the user-occupied and user-unoccupied frequency bands. The precise spectrum hole detection from the occupied spectral bands, with an added advantage of reduced hardware complexity, is an attractive feature of the proposed approach, that can effectively replace the existing filter bank-based detection methods. |
