Recently, it was shown that frequency-domain equalization (FDE) for the reception of single-carrier DS-CDMA signals is more effective than that of MC-CDMA systems in a frequency-selective fading channel. Both the theoretical analysis and computer simulation have proved that FDE based on minimum mean square error (MMSE) criterion provides the best BER performance with perfect channel information. However, the BER performances suffer from inevitable channel estimation error. For applications like mobile radio, the differential detection is preferable because of its simple implementation without any channel estimation at the receiver end. In this paper, we propose frequency-domain differential encoding and decoding (FDDED) for single-carrier DS-CDMA signal transmission in a frequency-selective fading channel. Compared with that of coherent FDE-MMSE, FDDED provides similar or even better BER performance especially for small spreading factor, SF (i.e., higher data rate for the given chip rate). |
