Abstract:

For odd n, the crosscorrelation function between a decimated DillonDobbertin (DD) sequence and WelchGong (WG) sequence is investigated, and the crosscorrelation function between a pair of Hyperoval sequences is studied. It is shown that the calculation of the crosscorrelation functions between a decimated DD sequence and WG sequence, and a pair of Hyperoval sequences could be reduced to the calculation of the crosscorrelation between msequences and their decimations. The crosscrrelation function between a decimated DD sequence and WG sequence could be 3valued under a 2k+1decimation.

Key words: crosscorrelation function, perfect sequences, decimation, DillonDobbertin sequence, WelchGong sequence, Hyperoval sequence
