【Abstract】 On basis of analyzing the multi-carrier CDMA technique,this paper expounds three schemes of the technique which realize it in detail:MC-CDMA,MC-DS-CDMA and MT-CDMA,and then concludes the advantages and disadvantages of each scheme.In order to compare the system features of the three schemes,this paper gives computer simulation and the result shows that the whole characteristic of MC-CDMA is better than MC-DS-CDMA and MT-CDMA because of its optimal distribution of spectrum and preferable capability of resisting interference.更多还原
