Abstract :
This paper describes the bit error rate (BER) performance of the multi-carrier CDMA modulation under the frequency selective fading. The multi-carrier CDMA signal is obtained by spreading the multi-carrier signal using the peculiar PN (pseudo random) code. The received multi-carrier CDMA signal is correlated and demodulated by the RAKE receiver. The output signal of the RAKE receiver is converted to subchannel signals through the discrete Fourier transform (DFT) and the received data is detected through the S/P (serial parallel converter). This paper clarifies that BER performance of the multi-carrier CDMA becomes 10-3 under the two multipath condition and a fading frequency of 100 Hz
