Polyphase sequences are finite, complex, time-discrete sequences with constant magnitude and variable phases. A polyphase sequence with elements of magnitude 1 is called a Barker sequence if the maximum magnitude of all sidelobes of their aperiodic auto-correlation function (ACF) is less or equal to one. Stochastic optimization algorithms have been applied to search for polyphase Barker sequenc...
