Otsm-based communication method, communication system, and computing device for performing the same

An orthogonal time sequency multiplexing (OTSM)-based communication method performed on a computing device including one or more processors and a memory storing one or more programs executed by the one or more processors, the OTSM-based communication method comprising:

• generating a plurality of candidate matrices in a delay-time domain by multiplying data in row units in a delay-sequency domain by a plurality of preset scrambled Walsh-Hadamard transform (S-WHT) matrices or generating a plurality of candidate matrices in a delay-time domain by scrambling the data in row units in the delay-sequency domain by using a plurality of preset scramble vectors and then multiplying the scrambled data by the S-WHT matrices;
• and
• generating a data matrix in the delay-time domain based on the plurality of candidate matrices.
