Title:
SIGNAL PROCESSING METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/083351
Kind Code:
A1
Abstract:
Disclosed are a signal processing method and a related device, used for estimating the strength of a passive intermodulation (PIM) signal. The method of the embodiments of the present application comprises: acquiring first downlink signal data corresponding to each of N cells under a preset bandwidth resource scheduling policy; determining first characteristic data corresponding to each first downlink signal data; and determining the strength of a first PIM signal corresponding to a first cell according to a preset signal strength evaluation model and the characteristic data corresponding to each of the N cells, such that the influence of the first PIM signal on the first cell can be estimated more accurately.
