  • Based on two arbitrary Hadamard matrices of common size, a new class of ternary sequence with aperiodic zero correlation zone is presented. Different from the construction given by Donelan and OFarrell, the proposed method can generate sequences with higher energy efficiency. Furthermore, two of this kind of sequence sets are constructed which are mutually orthogonal, so that the number of available sequences for a Qs-CDMA system is increased.
