Research on Construction Methods of Low Correlation zone Complementary Sequence Sets
Perfect complementary sequence is a kind of signal with ideal correlation function,which is widely used in multiple access communication system,radar waveform design and so on.However,the set size of perfect complementary sequences is at most equal to the number of its subsequences.In order to expand the number of complementary sequences,the construction methods of aperiodic low correlation zone complementary sequence set are studied in this paper.First,two kinds of mapping functions on finite fields are proposed,and then two kinds of low correlation zone complementary sequence set with asymptotically optimal parameters are obtained.The number of these kinds of low correlation zone complementary sequence set are more than that of the perfect complementary sequence set,thereby supporting more users in the communication system.
