1. A method method performed by a device and comprising:
generating at least one codeword by encoding an information block;
generating a scrambled bit sequence based on the at least one codeword;
generating data symbols based on the scrambled bit sequence;
processing the data symbols so that a first unique word (UW) discretely located in a frequency domain does not overlap with the data symbols in the frequency domain;
transmitting a first unique word (UW)-orthogonal frequency division multiplexing (OFDM) symbol that adds the data symbols, which are processed not to overlap, and the first UW discretely located in the frequency domain; and
processing the data symbols to overlap with a second UW in the frequency domain; and
transmitting a second UW-OFDM symbol that adds the data symbols processed to overlap and the second UW.
