چکیده
In this paper, we propose new methods of constructing optimal binary low correlation zone(LCZ) sequences. In the new method, we devise a column sequence set of length 2 − 1 from a binary sequence of period 2 − 1 having ideal autocorrelation property and this column sequence set is used to construct binary LCZ sequence sets of period 2n−1 when (m+1)|n. The new method gives us the optimal sets with respect to the bound by Tang, Fan, and Matsufuji. Finally, we propose a construction method of 2 × 2 binary Hadamard matrices from optimal LCZ sequence sets. key words: Binary sequence, Legendre sequence, low correlation zone(LCZ) sequence, sequence.

متن کاملA class of pseudonoise sequences over GF(P) with low correlation zone
b = 1. The index set I must be of the form I = A [ B [ C where A = f1g B = fz + 1 j z 2 C0; z + 1 2 C0g and C = f0z j z 2 C1; z + 1 2 C1g: Observe that these three sets are pairwise-disjoint. Therefore, The other cases can be treated similarly. ACKNOWLEDGMENT The authors wish to thank the anonymous referee for careful review of the original manuscript and helpful comments.

متن کاملNew Optimal p-ary Low Correlation Zone Sequences
In this paper, for integers n and e such that e|n and 2 − 1 is a prime, we propose a method of constructing binary low correlation zone (LCZ) sequences of period 2−1 by using the extended form sequence with the same period. These new LCZ sequences use Legendre sequences as their column sequences.
متن کاملAn Integrated Sequence Construction of Binary Zero-Correlation Zone Sequences
The present paper introduces an integrated construction of binary sequences having a zero-correlation zone. The cross-correlation function and the side-lobe of the auto-correlation function of the proposed sequence set is zero for the phase shifts within the zero-correlation zone. The proposed method enables more flexible design of the binary zerocorrelation zone sequence set with respect to it...
