Multi-Carrier (MC) modulation has recently evolved as an efficient modulation technique which can provide similar frequency diversity in the system. It is basically derived from orthogonal frequency division multiplexing (OFDM). Due to the dispersive nature of the mobile communications channels, MultiCarrier Code Division Multiple Access (MC-CDMA) signals will be affected by Inter channel interference (ICI), Inter symbol interference (ISI) and Multiple Access Interference (MAI). The precedent problems lead to the loss of subcarrier orthogonality. To solve the interference problem, a cyclic ext...
