Construction of asymptotic optimal LCZ sequence pairs set

Best binary sequence pair exists in a lager scope than perfect binary sequence,for the sake of enlarging the address code selection of Quasi-Synchronization Code Division Multiple Access(QS-CDMA).Two methods of constructing sequence pairs set of asymptotic optimal Low Correlation Zone(LCZ) were proposed.A kind of asymptotic optimal LCZ sequence pairs set was constructed based on perfect binary sequence pair with modified Walsh sequences set(or m-sequence's cyclic shift sequences set) and a set generated by the cyclic shift sequences of a binary sequence pair with two-level periodic autocorrelation.The asymptotic optimal LCZ sequence pairs set constructed have more various parameters combinations.It can provide more choices for engineering application.
