Title:
METHOD AND DEVICE FOR LOCATING INTERMODULATION POSITION
Document Type and Number:
WIPO Patent Application WO/2018/040101
Kind Code:
A1
Abstract:
The invention relates to the field of communications. Provided are a method and device for locating an intermodulation position capable of locating a position where intermodulation occurs. The device for locating an intermodulation position stores a mapping relationship between an intermodulation position and an intermodulation coefficient. The intermodulation coefficient is a relationship coefficient between a forward intermodulation signal and a reverse intermodulation signal of the same order. The device for locating an intermodulation position respectively acquires, from a test element, a first forward intermodulation signal and a first reverse intermodulation signal, determines the actual intermodulation coefficient according to the first forward intermodulation signal and the first reverse intermodulation signal, and determines, according to the stored mapping relationship, an intermodulation position corresponding to the actual intermodulation coefficient to be a position where intermodulation occurs.
