    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 pp, where pp is an odd prime with p≡1( mod  4)p\equiv 1(\bmod~4). The objective of this letter is to present a construction of binary sequences of period 4p4p 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
