1996 7200-phase generalized Barker sequences
abstract
We present 7200-phase generalized Barker sequences with lengths from 19 to 31. Also, we show the number of known M-phase generalized Barker sequences (M=7200), inequivalent under the group of "Barker-preserving transformations". The autocorrelation values of Barker sequences are also presented.

1994 On n-phase Barker sequences
abstract
An n-phase Barker sequence can be easily distinguished from the time-shifted versions of itself. This property is important for such applications as radar systems, synchronization systems, and spread-spectrum communications systems. The authors study some transformations on n-phase Barker sequences. Also, they give an efficient algorithm for finding sextic Barker sequences. Through an exhaustive computer search, numerical data for n-phase Barker sequences are given. Specifically, they extend the list of known n-phase Barker sequences to length L=19.>
