Hybrid low autocorrelation sequences (Corresp.)
Marcel E. Golay · IEEE Transactions on Information Theory · 1975
Skew-symmetric sequences of(2n + 1)terms,a_0,a_1,\cdots,a_{2n}, are described for which the "merit factor" \begin{equation} F_h = \frac{\biggl[\sum_{i=0}^{2n} \mid a_i \mid \biggr] ^2}{ 2 \sum_{k=1}^{2n} \biggl[ \sum_{i=0}^{2n-k} \text{sign} (a_i) \cdot a_{i+k} \biggl] ^2} \end{equation} is unusually high.
