Abstract :
A communication system with a combination of high order modulation and complementary sequences has lots of better properties, such as higher transmission data rates and spectrum efficiency, immunities to multiple access interference (MAI) and multi-path interference (MPI) synchronously, and so on. To satisfy the requirements of such a communication system, a construction method for yielding a family of 16-QAM periodic complementary sequence mates is presented in this paper. The proposed method transforms the known quaternary periodic complementary sequence (PCS) mates into the required 16-QAM ones. Due to a large number of available quaternary PCS mates, the resultant 16-QAM PCS mates are fairly rich.
