Balanced quaternary sequences of even period with optimal autocorrelation
Lianfei Luo, Wenping Ma · IET Communications · 2019
In many communication systems, sequences with low correlation can reduce interference and noise. Tang and Lindner presented a construction of low autocorrelation quaternary sequences of period p based on cyclotomy, where is a prime ( f , y are integers and ). In this study, a class of quaternary sequences of period 2 p are proposed via interleaving two Tang‐Lindner sequences of period p . New quaternary sequences of period 2 p are balanced and have optimal autocorrelation when .
