Published in 2018 at "Wireless Personal Communications"

DOI: 10.1007/s11277-017-5102-6

Abstract: Faster-than-Nyquist (FTN) transmission uses non-orthogonal pulses with respect to symbol time for improving system capacity and spectral efficiency. The Single Carrier Frequency-Domain Equalization (SC-FDE) system is an attractive transmission technique to combat the Inter-Symbol-Interference (ISI)… read more here.

Published in 2019 at "IEEE Access"

DOI: 10.1109/access.2019.2935758

Abstract: In this work, an estimation algorithm based on the compressive sensing (CS) technique is proposed for an orthogonal frequency division multiplexing (OFDM) system applied to multi-path time-varying channels. A fitting polynomial is used to approximate… read more here.

Published in 2022 at "IEEE Wireless Communications Letters"

DOI: 10.1109/lwc.2022.3192795

Abstract: In this letter, we propose faster-than-Nyquist (FTN) signaling transmission that is robust for an underwater acoustic (UWA) doubly selective channel. Owning to the explicit benefits of a reduced symbol interval specific to FTN signaling, the… read more here.
