Parallel Interference Cancellation Scheme in MC-CDMA over Frequency Selective Fading Channel

Abstract

From the past few years, the variant technologies of multi carrier code division multiple access (MC- CDMA) has gained importance in providing the broadband services through wireless communication. MC-CDMA could be a reliable technology wherever multiple users can communicate expeditiously in wireless medium. the key issue ought to be self-addressed within the MC-CDMA is multiple access interference (MAI) from totally different users. to beat this, the effective parallel interference cancellation mechanism is projected in this paper. in the initial stage, PIC is introduced to estimates the users interference. in the second stage, MMSE equalisation is employed to urge the users desired information. The projected methodology with success restricts the MAI and improved the performance of the MC-CDMA.
