The invention discloses a standing wave peak value determining method and equipment. The method comprises the steps of: acquiring a feedback signal generated after sending a multitone sweeping frequency signal; uniformly dividing the feedback signal into a plurality of measurement frequency bands and a plurality of sampling points according to frequency domains, wherein each measurement frequency band comprises a plurality of sampling points; based on processing on the feedback signal corresponding to each sampling point, determining a standing wave reflection peak value of the feedback signal corresponding to each measurement frequency band; and based on the standing wave reflection peak value in each measurement frequency band, determining a standing wave reflection peak value of the feedback signal in the entire frequency band. The standing wave peak value determining method and equipment implement accurate determination on the standing wave reflection peak value, and are also convenient for subsequently carrying out accurate determination of a standing wave ratio.
Description
technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular to a method and device for determining a standing wave peak value. Background technique [0002] VSWR (Voltage Standing Wave Ratio, voltage standing wave ratio) refers to the ratio of the standing wave voltage peak value to the voltage valley value. When the feeder and the antenna match, all the signal energy is absorbed by the load, and there is no reflected wave on the feeder; while when the impedance of the antenna and the feeder do not match, the load can only absorb part of the energy. Part of the energy of the incident wave is reflected back to form a reflected wave; resulting in the generation of standing waves; the greater the VSWR, the greater the reflection and the poorer the matching; therefore, the detection of the voltage standing wave ratio is a very important function in the base station system. Whether the actual working perfor...
