Abstract

This study investigates the throughput performance of faster-than-Nyquist (FTN) signaling in the presence of nonlinear distortion under multipath fading channels. In our performance evaluation, we use a practical transmission method, in which single-carrier with frequency-domain equalization (SC-FDE) is applied to FTN signaling for broadband wireless communications. For a radio propagation model, the 3GPP tapped delay line (TDL) model is used to evaluate the effect of multipath fading, and the Rapp model is adopted as a power amplifier (PA) model that provides the impact of nonlinear distortion. We compare the throughput performance of FTN signaling with that of Nyquist signaling under the same transmission rate via computer simulations, which clarifies the applicability of FTN signaling to practical broadband wireless communications.
