| 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 achieve a much improved bit error rate (BER) performance than using the conventional rake combining. MMSE-FDE requires accurate estimation of the channel transfer function, however, the BER performance degrades since the transfer function of pilot sequence does not stay constant. In this paper, pilot-assisted frequency-domain channel estimation based on MMSE criterion is proposed. The achievable BER performance using the proposed channel estimation is evaluated by computer simulation. |
