Generalized binary Udaya-Siddiqi sequences

Abstract

This paper presents the generalized Udaya Sidiqi sequences which are the interleaved version of Gold like binary sequences of period satisfying the Welch bound maximum out of phase correlations. The sequences have large linear complexity and low correlations and are useful in code division multiple access (CDMA) communication systems and cryptography. A direct method to compute the correlation using the trace sequence representation and a sequence from a quadratic form are presented.
