Title:
RECEIVER, RFID READING DEVICE, AND SIGNAL RECEIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/205956
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Disclosed are a receiver, an RFID reading device, and a signal receiving method. The receiver comprises a power distribution module, a frequency mixing module, and a filter. The power distribution module performs power division on a first radio frequency signal to obtain a second radio frequency signal and a first local oscillator signal; the frequency mixing module performs self-mixing on the second radio frequency signal and the first local oscillator signal, so as to obtain a third radio frequency signal; and the filter filters the third radio frequency signal, so as to obtain a fourth radio frequency signal. By means of the receiver, phase noise of a continuous-wave blocking signal and the amplitude of the continuous-wave blocking signal can be suppressed at the same time, such that while the blocking sensitivity of a receiving channel is improved, the dynamic solicitation of an ADC can be reduced, and the hardware cost of the receiver is reduced.
