Performance Comparisons of Faster-than-Nyquist Signaling Considering Fixed Utilized Bandwidth
In this study, we compare the system performance by considering faster-than-Nyquist (FTN) signaling employing single carrier frequency domain equalization (SC-FDE) and orthogonal frequency division multiplexing (OFDM) under the constraint of a fixed total utilized bandwidth. In this work, FDE also includes the appearance of colored noise, and the corresponding FDEs are formulated based on its effect to improve detection reliability. The advantages of FTN signaling and the preferable choices of compression and roll-off factors based on the bit error rate (BER) and system throughput are demonstrated under multipath fading channels via the simulation results.
