Abstract

In this paper, we analyze the signals of MC-CDMA system with linear combining for single user detection in a mulitpath Rayleigh fading channel. The multi-user interference (MUI) of other users is closely related with modulation methods. The multi-axes modulation scheme which rotates such one dimensional signaling as BPSK or ASK et al. is presented. It can be shown that MUI is effectively reduced by using this scheme. The proposed scheme has better performance up to 6 dB in E_b/N_o under reasonable assumption
