This paper presents receiver architectures and performance results relating to the UMTS (Universal Mobile Telecommunication System) TDD (time division duplex) mode. System performance in terms of uncoded BER (bit error rate) and overall capacity are compared for matched filter, RAKE and blind adaptive LMMSE receivers. Uplink comparisons are performed in a multi-user scenario over time varying frequency selective channels. In order to achieve high performance, a modified blind adaptive LMMSE receiver is proposed. Factors such as channel variation, interference suppression and low implementation complexity are considered. The results demonstrate that the proposed receiver architecture can greatly reduce the interference floor at the base station and thus significantly improve performance and capacity in the UMTS TDD mode.
