Single-carrier (SC) transmission with frequency-domain equalization (FDE) can be expect to expand the service area of wireless communication systems by taking advantage of its lower peak-to-average power ratio (PAPR) compared to when using orthogonal frequency division multiplexing (OFDM). However, in the uplink case, the transmit timing difference among the signals from multiple MTs becomes significant in a larger service area. If the difference in the arrival timing among MTs exceeds the guard interval (GI) length, it is difficult to separate the signal of each MT and the transmission quality is severely degraded. In this paper, we propose a novel multiuser detection (MUD) technique that can separate the signals regardless of the difference in the arrival timing between MTs and its achievable bit error rate (BER) performance is evaluated by computer simulation. |
