Abstract

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, we have shown that the use of frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can significantly improve the downlink BER performance. However, for the uplink transmissions, MAI (multi-access interference) is produced due to orthogonality destruction among users and the uplink BER performance severely degrades. In this paper, we propose a frequency-domain multi-stage MAI cancellation for DS-CDMA uplink with transmit/receive antenna diversity and evaluate the achievable BER performance by computer simulation.
