Interleaved Construction of Binary Sequences with Optimal Autocorrelation Magnitude
Nam Yul Yu, Guang Gong · 2006
New binary sequences of period N = 4(2m- 1) for even m ges 4 are found. These sequences can be described by a 4 times (2m- 1) interleaved structure. The new sequences are almost balanced and have four-valued autocorrelation, i.e., {N, 0, plusmn4}, which is optimal with respect to autocorrelation magnitude. Complete autocorrelation distribution of the sequences is mathematically derived
