METHOD, SYSTEM AND BASE STATION FOR DETECTING MUTUAL INTERFERENCE IN CO-ANTENNA FEEDING COMBINER

WIPO Patent Application WO/2017/101601

A1

Disclosed in the present invention are a method, a system and a base station for detecting mutual interference in a co-antenna feeding combiner. The method comprises: sequentially selecting to-be-detected channels from among all channels of the co-antenna feeding combiner to be detected; determining, according to the mutual modulation principle, whether mutual modulation exists between each detection frequency point of a to-be-detected channel and each detection frequency point of the other channels; determining, if it is determined that mutual modulation exists, whether mutual modulation products fall in a receiving band of the to-be-detected channel; and acquiring, if it is determined that mutual modulation products fall in a receiving band of the to-be-detected channel, all frequency points of the receiving band into which the mutual modulation products fall and the detection frequency point corresponding to each of the mutual modulation products. The present invention can effectively detect mutual interference in a co-antenna feeder system.
