Polyphase complementary codes
WebAug 30, 1990 · A new general construction for the complementary sets of polyphase and ternary sequences is presented. The new construction produces the so-called supercomplemetary sets of sequences, with some special additional properties. An important property of these sequences is the ambiguity function complementary property. … Web1 A Multiplier-free Generator for Polyphase Complete Complementary Codes Shibsankar Das, Student Member, IEEE, Srdjan Budiˇsin, Sudhan Majhi, Senior Member, IEEE,
