In this paper, the authors propose a new algorithm based on third order cumulants, for MultiCarrier Code Division Multiple Access (MC-CDMA) system equalization. In order to test its efficiency, they have compared with the (CUM-AZ) algorithm proposed in the literature, for that they considered five practical frequency-selective fading channels, called Broadband Radio Access Network (BRAN A, BRAN B, BRAN C, BRAN D, and BRAN E), normalized for (MC-CDMA) system, excited by non-Gaussian sequences. In the part of (MC-CDMA), they use the Zero Forcing (ZF) and the Minimum Mean Square Error (MMSE) equalizers techniques after the channel identification to correct the channel's distortion.
