Abstract

Abstract

In this paper, the clock-controlled sequence is presented as a potentially superior spreading code for A-CDMA systems. First, on the basis of an A-CDMA system modei, the relationship between the average bit error probability and the cross-correlation parameters of the PN (Pseudo Noise) sequences is established. The conditions, which the PN sequences as spreading codes should satisfy, are derived from the above relationship. Next, the feasibility of the clock-controlled sequences as the spreading codes for an A-CDMA system are analyzed systematically. Finally, the cross-correlation functions between m-sequence and clock-controlled sequence, as well as the average bit error probability (BEP) corresponding to both sequences under various user number, are compared in numerical results. The feasibility of the clock- controlled sequences as spreading codes is thus verified when U75.
