Title:
INTERFERENCE SIGNAL PARAMETER ESTIMATION METHOD AND DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/104457
Kind Code:
A1
Abstract:
An interference signal parameter estimation method and a detection device (700, 800, 900), which can rapidly and accurately estimate parameters of an interference signal, so as to avoid interference. Said method comprises: determining the slope of an interference signal, taking the slope of the interference signal as the slope of a first transmission signal, and determining parameters of the interference signal according to an echo signal feature of the first transmission signal. According to the feature that an interference with the same slope has a long interference duration and is stable, parameters, such as a period and a bandwidth, of an interference signal are determined more accurately, thereby better avoiding interference.
