Abstract
A receiver and a transmitter that copes with interference in a super-regenerative communication system, and a method of using the receiver and the transmitter, are provided. A super-regenerative receiver includes a resonance frequency adjusting unit configured to adjust a resonance frequency associated with a filtering band of a transmission signal that is received from a transmitter. The super-regenerative receiver further includes an oscillation signal generating unit configured to generate an oscillation signal, using a positive feedback amplification, based on the resonance frequency and the transmission signal. The super-regenerative receiver further includes an oscillation characteristic detecting unit configured to detect a characteristic of the oscillation signal. The super-regenerative receiver further includes a determining unit configured to determine whether interference is included in the transmission signal based on the characteristic of the oscillation signal and the resonance frequency.
