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)…

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…

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…
