This study proposes a faster-than-Nyquist (FTN) single-carrier multiple-input multiple-output (MIMO) signaling scheme considering the effects of colored noise. In this approach, frequency-domain equalization (FDE) is considered as a practical receiver. Moreover, since FTN signaling generally induces colored noise, the proposed scheme considers its impact on FDE weight generation for improved detection accuracy of FTN-MIMO signaling. The effectiveness of the proposed scheme is demonstrated in terms of both bit error rate (BER) and throughput via the compression factor parameters and MIMO antenna configuration through computer simulations.

This study investigates the throughput performance of fasterthan-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.
