Application of multicarrier CDMA to mobile communication technology

In a frequency selective fading environment, use of a single carrier for the transmission of the encoded data from the transmitter to receiver, causes signal distortion resulting in poor performance. But if the same encoded data is transmitted using more than one carrier then the received data from each subcarrier can be combined to achieve improved performance. This type of transmission is called a multicarrier (MC) code-division multiple access (CDMA) scheme. The advantages of an MC-CDMA approach are presented by the authors in this paper.
