Abstract(in English) | In direct sequence code division multiple access (DS-CDMA), frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can be applied to exploit the channel frequency-selectivity and therefore can replace the conventional rake combining with much improved bit error rate (BER) performance. However, the residual inter-chip interference (ICI) is present after MMSE-FDE and hence the achievable BER performance is degraded compared to the lower bound performance. We proposed a frequency-domain ICI cancellation that can significantly suppress the residual ICI. In this paper, we propose DS-CDMA turbo equalization in which frequency-domain ICI cancellation is incorporated into iterative turbo decoding. The achievable BER performance is evaluated by computer simulation. |
