  Abstract

In this paper, a new signal constellation design method is proposed for Multi-Phase(MP)/CDMA and its performance is compared with that of conventional method. In general MPSK modulation, the neighbor phases are allocated to the symbols that have only one different bit. However, the neighbor phases are allocated to the signal levels that have small differences in amplitude after clipping process since the transmitting signals in MP/CDMA are not binary symbols but the signal levels. The analysis shows that the performance of proposed scheme is much better than that of conventional method and it is better to increase the number of clipping levels than decrease the number of clipping levels and increase the region of guard phase.
