Odd-perfect, almost binary correlation sequences

Abstract

A set of perfect correlation sequences is discussed. The sequences are binary with exception of a single zero element and possess a perfect odd-autocorrelation function. The construction uses an isomorphy to special conference matrices and gives sequences with all lengths M=p/sup a/+1, p odd prime, a=1,2,... . Applications in CW radar and in measuring mobile radio channels are described using the ambiguity function of multiple odd-perfect sequences.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
