MULTI CARRIRER CODE DIVISION MULTIPLE ACCESS (MC CDMA)

ABSTRACT:

Orthogonal Frequency Division Multiplexing (OFDM) has recently gained a lot of attention and is a potential candidate for Fourth Generation (4G) wireless systems because it promises data rates up to 10Mbps. A variation of OFDM is Multi-Carrier CDMA (MC-CDMA) which is an OFDM technique where the individual data symbols are spread using a spreading code in the frequency domain. The spreading code associated with MC-CDMA provides multiple access technique as well as interference suppression.
MC CDMA is the basis for 4th generation systems. Starting with the introduction this paper gives the detailed study of MC CDMA ( multi carrier code division multiple access .

This paper gives the basic idea of OFDM( Orthogonal frequency division multiplexing). Further this paper explains the basics of CDMA. The combination of OFDM and CDMA is the MC CDMA. So this paper supports MC CDMA. This paper also describes the advantages of multi carrier modulation. Finally the applications of MC CDMA are described in detail.
