Binary sequences with orthogonal subsequences and a zero-correlation zone: Pair-preserving shuffled sequences
In this paper, we present a new approach to the construction of a set of binary sequences with a zero-correlation zone. The set consists of n pairs of binary sequences and the length of each binary sequence is n2((m+2)) for some integers m and n. The Hadamard sequences with length n are used to construct the set. Any sequence in the set has 2((m+1)) subsequences, each of length 2n. The author proves that any two subsequences are orthogonal if they belong to different pairs of binary sequences in the set.
