In this paper, the KMM¯ sequence (i.e., a clock-controlledsequence) is presented as a new spreading code for A-CDMA (Asynchronous CDMA)systems. The conditions, which PN sequence as spreading codes should satisfy,are given on the basis of an A-CDMA system model. The properties ofKMM¯ sequences are described and their feasibility as thespreading codes for an A-CDMA system are analysed. The computer simulationcompares the cross-correlation of m-sequence and KMM¯ sequenceto prove the good cross-correlation property of KMM¯ sequence.Numerical results show the impact of the m-sequence and the KMM¯sequence on the system performance, as well as the differences betweenm-sequences and KMM¯ sequences under different user number andprocessing gain for A-CDMA system. |
