A Design of NLOS Communication Scheme Based on SC-FDE with Cyclic Suffix for UAV Payload Communication

Drones
Non-line-of-sight (NLOS) communication with severe loss always leads to performance degradation in unmanned aerial vehicle (UAV) payload communication. In this paper, a UAV NLOS communication scheme based on single-carrier frequency domain equalization ...

Performance Evaluation of OTFS and OFDM in Rayleigh Fading Channel

Journal of Engineering, Volume 2026, Issue 1, 2026.
Orthogonal time–frequency space (OTFS) modulation is a crucial technology for addressing the challenges of 5G and 6G networks. OTFS was developed to address the problems of signal weakness and quality loss in mobile environments, such as those experienced by a user in a fast‐moving car or train; this is achieved by reducing intercarrier interference ...

Novel Intersymbol Interference Cancellation Scheme to Enable Parallel Computational and High-Performance Faster-Than-Nyquist Signaling

IEEE Access, 2017
In this paper, we deal with the intersymbol interference (ISI) cancellation problem induced by the faster-than-Nyquist (FTN) signaling. In the traditional FTN signaling, the detection delay at the receiver depends on the number of states of the ISI ...

Tropospheric Propagation Effects Extracted From ADS‐B Messages

Engineering Reports, Volume 7, Issue 12, December 2025.
This study explores the use of ADS‐B messages to estimate tropospheric effects, effectively isolating atmospheric influences from interference. The approach enables independent lower atmosphere studies and offers a cost‐free supplementary method for satellite applications, benefiting GNSS systems, especially at low elevation angles where multipath and ...

GRAND for Gaussian Intersymbol Interference Channels

CoRR
Channel decoding is a challenging task in communication channels exhibiting memory effects. In this work, we apply the recently proposed decoding paradigm of guessing random additive noise decoding (GRAND) to channels with memory, focusing on linear Gaussian intersymbol interference (ISI) channels.
