The Evolution of Faster-Than-Nyquist Signaling
IEEE Access, 2021 The fifty-year progress of faster-than-Nyquist (FTN) signaling is surveyed. FTN signaling exploits non-orthogonal dense symbol packing in the time domain for the sake of increasing the data rate attained.

Optimizing the Shape of Faster-Than-Nyquist (FTN) Signals With the Constraint on Energy Concentration in the Occupied Frequency Bandwidth [PDF]
IEEE Access, 2020 The achievement of the boundary values of spectral efficiency is associated with the development of methods for generating and receiving signals with a compact spectrum. The reason is a constant increase in the capacity of existing communication channels caused by an increase in the volume of transmitted information.

Performance Evaluation of MIMO-FTN Signaling Under Multipath Fading Channels
IEEE Access, 2023 In this paper, we investigate the advantages of multiple-input multiple-output (MIMO) faster-than-Nyquist (FTN) signaling under a fixed utilized bandwidth and multipath fading channels.

Deep Learning-based List Sphere Decoding for Faster-than-Nyquist (FTN) Signaling Detection
2022 IEEE 95th Vehicular Technology Conference: (VTC2022-Spring), 2022 Faster-than-Nyquist (FTN) signaling is a candidate non-orthonormal transmission technique to improve the spectral efficiency (SE) of future communication systems. However, such improvements of the SE are at the cost of additional computational complexity to remove the intentionally introduced intersymbol interference.

Dual pulse shaping transmission with sinc‐function based complementary Nyquist pulses
IET Communications, Volume 16, Issue 17, Page 2091-2104, October 2022., 2022 Abstract Due to difficulties in manufacturing, data conversion devices with extremely high sampling rate are becoming the bottleneck in realising high‐speed communication systems with a large bandwidth. Dual pulse shaping (DPS) transmission allows half‐symbol‐rate conversion devices to be used for two parallel data streams to achieve full‐rate ...

Journal of Geophysical Research: Space Physics, Volume 126, Issue 5, May 2021., 2021 Abstract We have conducted a statistical study of toroidal mode standing Alfvén waves detected by the Van Allen Probes spacecraft in the dayside inner magnetosphere, with an emphasis on the nodal structure of the fundamental through fifth harmonics. We developed a technique to accurately assign harmonic mode numbers to peaks in the power spectra of the

A Low‐Complexity and High‐Decoding Performance Scheme for the MIMO‐SCMA System
Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021 Sparse code multiple access (SCMA) has been proposed to obtain high capacity and support massive connections. When combined with the multiple‐input multiple‐output (MIMO) techniques, the spectrum efficiency of the SCMA system can be further improved. However, the detectors of the MIMO‐SCMA system have high computational complexity.
