Abstract

Faster-than-Nyquist (FTN) transmission uses non-orthogonal pulses with respect to symbol time for improving system capacity and spectral efficiency. The Single Carrier Frequency-Domain Equalization (SC-FDE) system is an attractive transmission technique to combat the Inter-Symbol-Interference (ISI) over frequency selective channel. In this paper, we investigate the FTN transmission in SC-FDE system over the multipath frequency selective channel. We design the transmission frame structure, and propose a receiving scheme with two concatenated equalizers to combat FTN-induced ISI and channel-induced ISI, respectively. The simulation results demonstrate that the Bit Error Rate performance can be improved with our proposed transceiver than that with just one equalizer at the receiver.
