Abstract :
The ideal transmission without multiple access interference (MAI) and multi-path interference (MPI) can be achieved in the next-generation CDMA wireless communication system by using complementary sequences, which can greatly improve the performance of such a system. Z-complementary sequences extend complementary sequences. In this paper, based on zero correlation zone (ZCZ) sequences, a new construction of Z-complementary sequences is presented. The trade-off among the width of ZCZ, the number and the length of sub-sequences of Z-complementary sequences can be made by choosing different values of parameter N, which will be suitable for various applied scenes.
