1. An electronic device, comprising:
an input unit configured to obtain a sequence to be compressed, wherein the sequence to be compressed has Q time-domain symbol elements, and Q is an integer greater than zero;
a processing unit configured to perform a zero-padding operation on the sequence to be compressed according to at least a part of a compression factor to determine a zero-embedded sequence, perform a discrete Fourier transform spreading operation according to the zero-embedded sequence to determine a spread sequence, and perform at least one of a data deletion operation and a data superimposition operation based on the spread sequence to determine a compressed sequence, wherein the compressed sequence has M frequency-domain symbols, M is an integer greater than zero, and M is less than or equal to Q.
