Abstract

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.
