The merit factor of optimally decimated and shifted Chu and Frank sequences was determined. These are perfect sequences, i.e. the out-of-phase values of their periodic autocorrelation functions (PACF) vanish. However, this property does not correspond to a large merit factor, which is defined as the ratio of the squared energy of the sequence to the sum of the squared sidelobes in their aperiodic...
Polyphase sequences are time-discrete complex sequences with constant magnitude and variable phase. In this letter polyphase sequences with aperiodic autocorrelation function (ACF) sidelobes of values less than or equal to 1 are presented. Such sequences are called Barker sequences. Binary Barker sequences with elements 1 or -1 are only known up to 13 elements. Now, with an iteration scheme, polyphase...
