Query: New Optimal Binary Sequences with Period $4p$ via Interleaving
  Ding-Helleseth-Lam Sequences   Binary sequences with optimal autocorrelation play important roles in radar,
communication, and cryptography. Finding new binary sequences with optimal
autocorrelation has been an interesting research topic in sequence design.
Ding-Helleseth-Lam sequences are such a class of binary sequences of period
$p$, where $p$ is an odd prime with $p\equiv 1(\bmod~4)$. The objective of this
letter is to present a construction of binary sequences of period $4p$ via
interleaving four suitable Ding-Helleseth-Lam sequences. This construction
generates new binary sequences with optimal autocorrelation which can not be
produced by earlier ones.
