Pre-Equalized Interference Cancellation for Faster-Than-Nyquist Signaling
IEEE Access, 2019 An affine projection (AP)-based equalizer (APE) is introduced to eliminate the inter-symbol interference (ISI) for faster-than-Nyquist (FTN) signaling. Based on the APE, a pre-equalized interference cancellation (PIC) algorithm is proposed to eliminate ...

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.

BER performance of finite in time optimal FTN signals for the Viterbi algorithm
Journal of Electronic Science and Technology, 2020 In this article, we consider the faster than Nyquist (FTN) technology in aspects of the application of the Viterbi algorithm (VA). Finite in time optimal FTN signals are used to provide a symbol rate higher than the “Nyquist barrier” without any encoding.
