As the number of resolvable propagation paths increases, the bit error rate (BER) performance of DS-CDMA with rake combining degrades due to increasing inter-path interference. Recently, it has been found that using the frequency-domain equalization (FDE) can improve the BER performance. However, in the uplink transmissions, MAI (multi-access interference) is produced due to orthogonality destruction among users and the BER performance severely degrades. In this paper, we propose frequency-domain MAI cancellation for DS-CDMA uplink and the achievable BER performance is evaluated by computer simulation. |
