摘要

A channel-selective super regenerative receiver (SRR) system is proposed with improved channel selectivity. The proposed SRR system operates only at a valid incoming signal due to the RF spectrum sensing functionality. To overcome the rough channel selectivity of the SRR, a systemic methodology is proposed for controlling quenching signal waveforms. From the experimental evaluations, the proposed system presented excellent channel selection capability of the 3.5-MHz channel bandwidth. The proposed architecture can allocate at least three times the number of channels for cognitive IoT sensor networks as that of previous ones.
