| Abstract(in English) | A modification of transmit filtering in single-carrier (SC) transmission contributes to an improvement of system performance in terms of peak-to-average power ratio (PAPR) and bit error rate (BER). Using minimum mean-square error based frequency-domain equalization (MMSE-FDE) at the receiver can combat the problem of inter-symbol interference (ISI) arising from channel frequency-selectivity. In this paper, instead of conventional transmit and receive filters, we propose an excess-bandwidth joint transmit/receive FDE. Transmit FDE weight (Tx-FDE) is determined jointly with receive FDE (Rx-FDE) in a suboptimal approach. Excess-bandwidth transmit filtering also leads to the additional frequency diversity gain when MMSE-FDE with spectrum combining is used at the receiver. Performance evaluation of the proposed transmission scheme is shown in terms of PAPR, BER, and system throughput, with the variation of transmit roll-off factor. |
