Title:
SIGNAL PROCESSING METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/000196
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provides a signal processing method and apparatus, a device, and a storage medium. The method comprises: a sending end sending a frequency hopping sensing signal on N time units, the frequency hopping sensing signal comprising N sub-sequences belonging to a first sequence, wherein N is a positive integer, time units occupied by any two sub-sequences in the N sub-sequences are different, and the frequency domain ranges occupied by any two sub-sequences in the N sub-sequences are different; and a receiving end receiving the frequency hopping sensing signal on the N time units. According to embodiments of the present application, by providing a frequency hopping sensing signal, the positioning, sensing, imaging, etc. of a target to be detected can be implemented without a need for said target to have a communication function. Moreover, the frequency hopping sensing signal uses a segmented frequency hopping transmission mode, such that a device having a limited working bandwidth and/or limited power can also provide high-precision positioning and sensing capabilities.
