Abstract :
The multi-carrier (MC) CDMA technique can reduce the interference and improve the performance of the system in fading channels. In this paper, to transmit high rate data, an improved novel M-ary MC-CDMA technique is proposed, which offers a much higher spectral efficiency. We give numerical results of the performance analysis and comparisons of conventional MC-CDMA schemes with the proposed M-ary MC-CDMA in an uplink channel with frequency-selective Rayleigh fading.
