Constructions of Balanced Quaternary Sequences of Even Length

摘要


Pseudorandom sequences with good autocorrelation properties have been widely used in communications, cryptography, and other digital systems. In this paper, for odd prime N, new balanced quaternary sequence of even period 2N is constructed using Gray mapping. The distribution of autocorrelation function of the proposed quaternary sequence is also derived. Specially, a new class of balanced quaternary sequence with optimal autocorrelation value is obtained under certain condition.
