Self-Orthogonal Finite-Length Sequence and Its Derived Sequences

摘要

A finite-length sequence with impulsive autocorrelation function of no sidelobes except at shift ends can be called a self-orthogonal or shiftorthogonal finite-length sequence. This paper describes the general solution for the sequence and the orthogonal sets of the sequences. The sequences are constructed by the convolution of element sequences. The orthogonal sets are applicable to synchronous or quasi-synchronous CDMA system which suppresses intersymbol and intracell interferences and makes digital convolution or correlation processing fast.
