| Abstract(in English) | To improve the bit error rate (BER) performance of direct sequence code division multiple access (DS-CDMA), fast Fourier transform (FFT) can be applied to the received signal sequence to carry out joint frequency-domain equalization (FDE) and antenna diversity combining. We have reported that the application of FDE to DS-CDMA can significantly improve the BER performance for a large spreading factor SF. However, inter-chip-inference (ICI) cannot be sufficiently suppressed for the case of small SF. In this paper, we propose three types of ICI canceller based on minimum mean square error (MMSE)-FDE and maximal ratio combining (MRC)-FDE, and evaluate the average bit error rate (BER) performance by computer simulation. |
