Low Complexity Message Passing Receiver for Faster-Than-Nyquist Signaling in Nonlinear Channels

open access: yesIEEE Access, 2018
The modern and future communication systems demand higher data rate exceeds current capabilities. Faster-than-Nyquist (FTN) signaling is a promising technique for the reason it can improve the spectral efficiency.

Successive interference cancellation in multistream faster-than-Nyquist Signaling [PDF]

open access: yesProceedings 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.

On Information Rates Over a Binary-Input Filtered Gaussian Channel

open access: yesIEEE Open Journal of the Communications Society, 2021
We study communication systems over band-limited Additive White Gaussian Noise (AWGN) channels in which the transmitter’s output is constrained to be symmetric binary (bipolar).

Capacity limit for faster-than-Nyquist non-orthogonal frequency-division multiplexing signaling

open access: yesScientific Reports, 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.

Non Binary and Precoded Faster Than Nyquist Signaling [PDF]

open access: yesIEEE Transactions on Communications, 2008
Faster than Nyquist (FTN) signaling is an important method of narrowband coding. The concept is extended here to non binary signal constellations; these are much more bandwidth efficient than binary ones. A powerful method of finding the minimum distance for binary and non binary FTN is presented.
