| Abstract(in English) | In asynchronous DS/CDMA, we discuss me performance of the system, in which each transmitting signal power is assigned with expornential law and multiple access interference(MAI) successive cancellation techniques are adopted in the receiver. In the system, when the number of multiple access users increases, the propagation error which arises in relation to MAI cancellation error of the front stage of MAI cancellation occurs, and me spectral efficiency is decreased by its influence. In this paper, considering the propagation error in successive cancellation, we propose a novel method to decrease these error in the receiver. And we evaluate its performances by computer simulations and show that the proposed system is effective for reduction of the propagation error. |
