| Abstract(in English) | The peak-to-average power ratio (PAPR) of Nyquist filtered single carrier (SC)-FDMA signal can be reduced by increasing the filter roll-off factor a. Furthermore, an additional frequency diversity gain can be obtained by making use of the excess bandwidth introduced by the transmit filtering. If the carrier-frequency separation is kept the same as in the case of α=0, the larger multiuser interference (MUI) is produced due to the spectrum overlapping when α>0. Frequency-domain iterative successive MUI cancellation (FD-ISMUIC) can achieve the bit error rate (BER) performance close to the single user case when QPSK data modulation is used. However, when 16QAM data modulation is used, a BER floor appears. In this paper, we apply antenna diversity to the uplink filtered SC-FDMA using FD-ISMUIC and the achievable BER performance is evaluated by computer simulation to confirm the effectiveness of antenna diversity when 16QAM data modulation is used. |
