A Barker sequence is a sequence with elements +1 such that all out-of-phase aperiodic autocorrelation coefficients are 0, 1 or -1. It is known that ifa Barker sequence of length s > 13 exists then s = 4N 2 for some odd integer N \_> 55, and it has long been conjectured that no such sequence exists.
