Title:
BLIND SCAN METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/205931
Kind Code:
A1
Abstract:
Provided in the application are a blind scan method and a device, relating to the technical field of communication. The blind scan method and a device are used to solve the problem that the prior art is not applicable to fast blind scanning of DVB-S2X satellite signals. The method comprises the following steps: a receiver acquiring a signal of a frequency band to be measured; on the basis of a frequency to be measured and a symbol rate to be measured, selecting two frequency spectrum segments from a spectrum corresponding to the signal of the frequency band, the two frequency spectrum segments being symmetric on the basis of the center frequency of the frequency to be measured, and the distance from the center frequency of the two frequency spectrum segments to the frequency to be measured being determined by the symbol rate to be measured; then, calculating a correlation value between the two spectrum segments; and if the correlation value between the two spectrum segments is greater than a preset value, determining that the frequency to be measured and the symbol rate to be measured are a set of candidate channel parameters. This application is applicable to the process of blind scanning.
