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 …

Constant Amplitude (CA), Zero Auto Correlation (ZAC) sequences (or CAZAC sequences,
aka perfect sequences) have numerous applications. We generalize the CAZAC notion to …

In this paper, we survey constructions of and nonexistence results on combinatorial/
geometric structures which arise from unions of cyclotomic classes of finite fields. In …

In 1998, Lin presented a conjecture on a class of ternary sequences with ideal two-level
autocorrelation. Those sequences have a very simple structure, ie, their trace representation …

Purpose: To investigate more fully, than what was done in the past, certain families of
symmetric Hadamard matrices of small orders by using the so called propus construction …

A Gaussian integer is a complex number whose real and imaginary parts are both integers.
This paper proposed a unified construction of perfect Gaussian integer sequences based on …

In this paper, we present some construction methods for punctured binary array/sequence
pairs (PBAPs/PBSPs) with ideal/optimal correlation constant using their algebraic …

We present a survey on the current status of the constructions of polyphase sequences with
low correlation, discrete Fourier transform (DFT), and ambiguity in both time and phase …

In this Letter, two constructions of new binary sequences with optimal autocorrelation
magnitude of length 4N derived from binary sequences with optimal autocorrelation of …

Pairs of complementary binary or quaternary sequences of length v such as Golay pairs,
complex Golay pairs and periodic Golay pairs may be used to construct Hadamard matrices …
