Most coding theory experts date the origin of the subject with the 1948 publication of A
Mathematical Theory of Communication by Claude Shannon. Since then, coding theory has …

Tang and Ding\cite {X. Tang} present a series of quaternary sequences $ w (a, b) $
interleaved by two binary sequences $ a $ and $ b $ with ideal autocorrelation and show …

In 2008, a class of binary sequences of period N= 4 (2^ k-1)(2^ k+ 1) N= 4 (2 k-1)(2 k+ 1)
with optimal autocorrelation magnitude has been presented by Yu and Gong based on an m …

Let be an additive group of order. A-element subset of is called a-almost difference set if the
expressions, for and in, represent of the non-identity elements in exactly times and every …

Pseudorandom sequences with low autocorrelation magnitude play important roles in
various environments. Let N be a prime with N= Mf+ 1, where M and f are positive integers. A …

Some pseudorandom sequences with good crytographic features can be obtained from the
interleaving of other families of sequences with unsuitable properties. PN-sequences …

In this paper, we construct some balanced quaternary sequences of odd period p with low
autocorrelation from two types of Legendre sequences and its cyclic shift or complement and …

Binary periodic sequences with good autocorrelation property have many applications in
many aspects of communication. In past decades many series of such binary sequences …

Pseudorandom sequences with low autocorrelation, high linear complexity and m-adic
complexity, are widely used in many areas of communication and cryptography. Since the …
