Abstract:

A new class of binary sequence pair sets with zero correlation zone (ZCZ) is constructed by interleaving characteristic sequences from quadratic difference set (4t-1,2t-1,t-1)DS and sequence pairs from difference set pair (N,p,q,e,λ)DSP. This method solves the problem that some nonbinary elements exist in the binary sequence pair sets with ZCZ constructed so far. Meanwhile, by selecting the appropriate difference set pairs, the proposed binary sequence pair sets with ZCZ can achieve satisfactory energy efficiency in mismatched filtering.
