Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/015450
Kind Code:
A1
Abstract:
Provided in the present disclosure is an electronic device. The electronic device comprises: an input unit, which is configured to obtain a sequence to be compressed, wherein the sequence to be compressed has Q time-domain symbol elements, Q being an integer greater than 0; and a processing unit, which is configured to perform, according to at least part of a compression factor, a zero-padding operation on the sequence to be compressed, so as to determine a zero-embedding sequence, to perform a discrete Fourier transform spread operation according to the zero-embedding sequence, so as to determine a spread sequence, and perform at least one of a data deletion operation and a data superposition operation on the basis of the spread sequence so as to determine a compressed sequence, wherein the compressed sequence has M frequency-domain symbols, M is an integer greater than 0, and M is less than or equal to Q.
