| Abstract: | In this paper we introduce a new wireless telecommunication technology: DFDM based multi-carrier CDMA system. We present its structure and characteristics, and compare it with CDMA system. In the end we draw a conclusion that MC-CDMA is much better than CDMA, and MC-CDMA has the advantages in spectral frequency, anti-interference ability, channel estimating and power controlling. This technology will have good application prospect in the future. |
