Document Type and Number:
WIPO Patent Application WO/2023/185719
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and discloses a signal transmission method and apparatus, a sending end device, and a receiving end device. The signal transmission method of embodiments of the present application comprises: a sending end device performs inverse symplectic Fourier transform (ISFFT) on a delay-Doppler domain signal to obtain a time-frequency domain signal; the sending end device performs scrambling processing on the time-frequency domain signal to obtain a scrambled time-frequency domain signal; the sending end device converts the scrambled time-frequency domain signal into a time domain signal; and the sending end device sends the time domain signal.
