Recently, the MC-CDMA technique based on the combination of conventional CDMA and OFDM technique has attracted great interest in both practical and theoretical studies of modern mobile communication because of its high spectral efficiency and high data transmission. A turbo coded Discrete Wavelet Packet Transform DWPT based Multicarrier CDMA system has been proposed to enhance the bit error rate and complexity of the conventional MC-CDMA which based on Fast Fourier Transform FFT over different channel models.
