Differential Faster-Than-Nyquist Signaling
IEEE Access, 2018 In this paper, we propose a novel differential faster-than-Nyquist (DFTN) signaling concept that allows us to dispense with any channel estimation at the receiver, while benefiting from a rate boost specific to faster-than-Nyquist (FTN) signaling.

Capacity limit for faster-than-Nyquist non-orthogonal frequency-division multiplexing signaling. [PDF]
Sci Rep, 2017 Faster-than-Nyquist (FTN) signal achieves higher spectral efficiency and capacity compared to Nyquist signal due to its smaller pulse interval or narrower subcarrier spacing. Shannon limit typically defines the upper-limit capacity of Nyquist signal.

Faster-Than-Nyquist Asynchronous NOMA Outperforms Synchronous NOMA [PDF]
IEEE Journal on Selected Areas in Communications, 2022 Faster-than-Nyquist (FTN) signaling aided non-orthogonal multiple access (NOMA) is conceived and its achievable rate is quantified in the presence of random link delays of the different users. We reveal that exploiting the link delays may potentially lead to a signal-to-interference-plus-noise ratio (SINR) gain, while transmitting the data symbols at ...
