| 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 combining when α>0. Frequency-domain iterative parallel MUI cancellation (FD-IPMUIC) can prevent the bit error rate (BER) performance degradation when a is small. However, when a approaches 1, a BER floor appears. In this paper, we propose a frequency-domain iterative successive interference cancellation (FD-ISMUIC) with the received signal power based ordering for the uplink filtered SC-FDMA. The introduction of the received signal based ordering makes it possible to generate more accurate MUI replicas to be used in FD-ISMUIC and better BER performance can be achieved using with smaller number of iterations. The achievable BER performance and throughput performance are evaluated by computer simulation to confirm the effectiveness of the received signal power based ordering. |
