Abstract: A method of a first communication node may comprise: generating a first sequence that is a maximal length sequence having a length of 2n−1 for a positive integer n; generating a second sequence having a relationship of a preferred pair with the first sequence; generating a third sequence having a relationship of a preferred pair with the first sequence and the second sequence; and generating a binary sequence group using the first to third sequences.

Abstract: A method of a first communication node may comprise: generating a first intermediate base sequence consisting of M elements based on first, second and third binary sequences, wherein M is a natural number; generating a second intermediate base sequence consisting of M elements by modifying the first intermediate base sequence; generating a base sequence consisting of 2M elements based on distributed concatenation of the first intermediate base sequence and the second intermediate base sequence; mapping modulation symbols generated by modulating the base sequence to 2 (M+1) subcarriers; and transmitting a signal consisting of the mapped modulation symbols to a second communication node.
