A novel Method to access QA In EducationEnvironment

Abstract— A novel Method to access QA In EducationEnvironment. In this paper, a novel access method with LS-code in multicarrier code division multiple access (MC-CDMA) system is proposed, called MC-LS-CDMA scheme. The theoretical analysis and the simulation results show that by using the LS-code access method proposed here, the sensitivity to frequency offset in the MC-CDMA system can be effectively eliminated. The benefit is because of the interference free window (IFW) in LS-code.
