Crosscorrelations of Franksequences and Chu sequences
Pingzhi Fan, Matthew E. Darnell, B. Honary · Electronics Letters · 1994
Sets of Frank sequences and Chu sequences are two classes of polyphase sequence with ideal periodic autocorrelation functions, which at the same time have optimum crosscorrelation functions. In the Letter, the crosscorrelations of sets of combined Frank/Chu sequences, which contain a larger number of sequences than either of the two constituent sets, are considered. It is shown analytically that the crosscorrelations are similar to those of the original sets with one exception, while the autocorrelations remain perfectly impulsive.
