Abstract
This paper focuses on investigation of periodic complementary sequence sets over quadrature amplitude modulation (QAM) constellation. We propose a method converting existing binary mutually uncorrelated complementary sequence sets (MUCSSs) into required sequence sets, and discuss family size of the resultant sequence sets. More clearly, the number of new sequence sets is an exponent of period of sub-sequences. Hence, our method can provide a large number of candidates for applications of CDMA or OFDM communication systems in elimination of multiple access interference (MAI) or reduction of peak envelope power(PEP), respectively.
