A generalized construction of quaternary periodic complementary sequence sets

Based on a binary periodic complementary sequence sets (PCSSs) with odd period N of sub-sequences, a generalized construction of quaternary PCSSs is presented. The proposed construction includes the known one in [1] as a special case, and the number of the resultant distinct quaternary PCSSs is N times as many as the one of the latter. As in [1], however, the resulting quaternary PCSSs have an expanded period 2N of sub-sequences, which is the cost paid for these new advantages.
