Title:
SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/088508
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a signal processing method and apparatus, relating to the field of communications, and solving the problem of how to reduce adjacent channel interference caused by an access link on a backhaul link without changing the structure of a device. The specific solution is as follows: a backhaul node receiving an adjacent channel interference signal within a first frequency band, and acquiring an adjacent channel interference reference signal, the first frequency band being a frequency band used by the backhaul node to receive a downlink signal, the adjacent channel interference signal including an intermodulation component within the first frequency band, the intermodulation component within the first frequency band being obtained by the access node after performing baseband processing, digital and analog processing and power amplification on a received first downlink signal, the adjacent channel interference reference signal including the intermodulation component within the first frequency band; performing adjacent channel interference cancellation processing on the adjacent channel interference signal according to the adjacent channel interference reference signal, to obtain the signal on which the adjacent channel interference cancellation has been performed. Thus, the present invention reduces the adjacent channel interference caused by the access link on the backhaul link. The embodiments of the present application are applied to signal processing processes.
