Abstract(in English) | The downlink bit error rate (BER) performances of DS- and MC-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. However, the uplink BER performance degrades due to strong multi-user interference (MUI) since different users' signals go through different channels and hence the orthogonality among user is distorted. In this paper, we apply joint orthogonal frequency-interleaving and MMSE-FDE to turbo coded DS- and MC-CDMA and their uplink BER performances are evaluated by computer simulation. |
