Multistream Faster than Nyquist Signaling [PDF]
IEEE Transactions on Communications, 2009 We extend Mazo's concept of faster-than-Nyquist (FTN) signaling to pulse trains that modulate a bank of subcarriers, a method called two dimensional FTN signaling. The signal processing is similar to orthogonal frequency division multiplex(OFDM) transmission but the subchannels are not orthogonal.

Coordinate Interleaved Faster-Than-Nyquist Signaling
IEEE Communications Letters, 2023 Faster-than-Nyquist (FTN) signaling is an attractive transmission technique which accelerates data symbols beyond the Nyquist rate to improve the spectral efficiency; however, at the expense of higher computational complexity to remove the introduced intersymbol interference (ISI). In this work, we introduce a novel FTN signaling transmission technique,

Constrained Capacities for Faster-Than-Nyquist Signaling [PDF]
IEEE Transactions on Information Theory, 2009 This paper deals with capacity computations of faster-than-Nyquist (FTN) signaling. It shows that the capacity of FTN is higher than the orthogonal pulse linear modulation capacity for all pulse shapes except the sinc. FTN signals can in fact achieve the ultimate capacity for the signal power spectral density (PSD).

Joint Rx IQ Imbalance Compensation and Timing Recovery for Faster-than-Nyquist WDM Systems
PhotonicsFaster-than-Nyquist (FTN) tight filtering introduces serious inter-symbol interference (ISI) impairment, leading to an insufficient compensation range for conventional IQ imbalance compensation algorithms.

Successive interference cancellation in multistream faster-than-Nyquist Signaling [PDF]
Proceedings of the 2006 international conference on Wireless communications and mobile computing, 2006 In earlier work we have extended Mazo's concept of faster than-Nyquist signaling to pulse trains that modulate adjacent subcarriers, a method we called two dimensional Mazo signaling. The signal processing is similar to orthogonal frequency division multiplex (OFDM) transmission.

IEEE AccessThe adoption of one-bit analog-to-digital converters (ADCs) in wireless communication has become increasingly popular, owing to their potential to reduce power consumption. However, there is a decreased spectral efficiency (SE) associated with their use,
