Title:
FREQUENCY SPECTRUM SENSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/056083
Kind Code:
A1
Abstract:
Disclosed in the present application are a frequency spectrum sensing method and device. The method comprises: sending a preamble signal over a target channel on the basis of a first transmitting gain; on the basis of a normal mode, receiving a mixed signal containing the preamble signal, and separating the mixed signal by using a fitting separation method to obtain a target signal; generating frequency spectrums of the target channel according to the target signal; splicing the frequency spectrums by means of channel impulse response splicing to obtain a high-definition frequency spectrum; and on the basis of the high-definition frequency spectrum, determining the occupation state of the target channel.
