Orthogonal finite-length sequence sets with impulsive autocorrelation function

Abstract

- Self-orthogonal finite-length sequence has impulsive autocorrelation function with no sidelobes except at both shift ends. In this paper, sets of self-orthogonal finite-length sequences with and without zero-correlation zone are presented for the application to synchronous or quasi--synchronous CDMA communication system without interferences. Sequence set starting from a pair of sequences of length 5 as well as other sets are derived from general solution for a sequence which is given by the sequence spectrum composed of primitive sequence spectra. Derived sequences are applicable to fast convolution or correlation processing.- Self-orthogonal, finite-length, pseudonoise sequence, zero-correlation zone,
