Simulation and Technology of Multi-carrier CDMA Based on OFDM

Liang Zhao

Abstract

This paper constructs multi-carrier CDMA system.There are three schemes in the Multi-Carrier CDMA,(MC-)CDMA,MCDS-CDMA and MT-CDMA.We take MC-CDMA,MC-DS-CDMA for example,the performance of the system in AWGN and Rayleigh channel is calculated,and numerical results are analyzed.As the result showed,the performance of MCCDMA system is superior to MC-DS-CDMA.
