Current wireless communication systems rely on the assumptions of the Nyquist theorem. Faster-Than-Nyquist (FTN) assumes that a bandwidth below the Nyquist bandwidth can be used with minimum loss, however the existing receivers are too complex. Single Carrier with Frequency-Domain Equalization (SC-FDE) has been proposed to handle multipath dispersive broadband channels, however the uplink of SC-FDE can be severely affected by deep-fades and/or poor channel conditions. To cope with such difficulties Diversity Combining (DC) Hybrid ARQ is a viable technique, since it combines the several packet copies sent by a Mobile Terminal to create reliable packet symbols at the receiver. This paper proposes a simple SC-FDE Packet Error Rate analytical model using FTN signaling, based on the Iterative Block with Decision Feedback Equalization technique, which achieves a performance similar to Nyquist signaling.
