Abstract:

Based on a pair of Hadamard matrices of the same size, a new construction of mutually orthogonal binary sequence sets with zero correlation zone (ZCZ) is presented by interleaving recursion. The sequence sets proposed can achieve theoretical bound of binary ZCZ sequence sets. By interleaving recursion, ZCZ sequence sets can be constructed from Hadamard sequences weighted by the coefficient matrices, satisfying mutually orthogonality, in which the number of sequences doubles the size of Hadamard matrix. The construction results illustrate that the proposed method improves the number of mutually orthogonal binary sequence sets with ZCZ and obtains more new sequence sets, which are used in quasi-synchronous code division multiple access system and implemented conveniently in hardware, by means of different choices of the coefficient matrices.

Key words: Hadamard matrices, zero correlation zone, interleaving recursion, mutually orthogonal, coefficient matrices
