AUTOCORRELATION FOR A CLASS OF POLYNOMIALS WITH COEFFICIENTS DEFINED ON T

Abstract

In this work we deal with the coefficients of A (e it ) 2 , where A is in a class of polynomialshaving Unimodular coefficients. We first present a technique that calculates lower bounds for particularautocorrelations and then in a more general case we present an upper bound for their maximal order.
