Standing wave detection method, standing wave detection apparatus and base station

A standing wave detection apparatus, comprising:

• a collecting module, configured to collect a feedback signal from a feedback path of a base station that uses a baseband multi-tone signal as a transmission signal;
• a calibrating module, configured to perform calibration processing on the feedback signal by using stored calibration data to obtain a reflected signal in the feedback signal, wherein the stored calibration data comprises baseband multi-tone signals and corresponding feedback signals respectively collected when a calibration point is in a state of open-circuited, short-circuited, and matched load;
• and
• a detecting module, configured to obtain a standing wave detection value according to the transmission signal and the reflected signal that is in the feedback signal.

A computer program product comprising a computer readable non-transitory storage medium storing program code thereon for use by a base station, the program code comprising:

• instructions for collecting a feedback signal from a feedback path of a base station that uses a baseband multi-tone signal as a transmission signal;
• instructions for performing calibration processing on the feedback signal by using stored calibration data to obtain a reflected signal in the feedback signal, wherein the stored calibration data includes baseband multi-tone signals and corresponding feedback signals respectively collected when a calibration point is in a state of open-circuited, short-circuited, and matched load;
• and
• instructions for obtaining a standing wave detection value according to the transmission signal and the reflected signal that is in the feedback signal.
