Abstract— The bit error rate (BER) performance of DS-CDMA in a frequency-selective fading channel can be significantly improved by the use of frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion. Accurate estimation of the channel transfer function and the signal-to-noise power ratio (SNR) are necessary for MMSE-FDE. Direct application of pilot-assisted channel estimation (CE) degrades the BER performance, since the frequency spectrum of the pilot chip… CONTINUE READING
