Analytic investigation into the statistical characteristics of the interference due to non-orthogonal time–frequency signaling

open access: yesEngineering Science and Technology, an International Journal, 2017
The statistical characteristics of non-truncated Intersymbol and Interchannel Interference (ISI/ICI) due to Non-Orthogonal Time-Frequency Signaling (NOTFS) are analytically investigated. The Gaussianity of ISI/ICI is formally discussed in general.

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

open access: yesIEEE 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 ...

Efficient Sequence Detection of Multicarrier Transmissions over Doubly Dispersive Channels

open access: yesEURASIP Journal on Advances in Signal Processing, 2006
We propose a high-spectral-efficiency multicarrier system for communication over the doubly dispersive (DD) channel which yields very low frame error rate (FER), with quadratic (in the frame length) receiver complexity.

8/10 two‐dimensional modulation code for holographic data storage systems

open access: yesElectronics Letters, 2016
Holographic data storage (HDS) provides the high storage density and fast data‐access rate because of the page‐oriented data processing, and by the same reason, the performance of retrieving original user data is mainly affected by 2D intersymbol ...

Pilot‐Based Iterative Path Estimation and Maximum Ratio Combining (MRC)–Based Signal Detection of Orthogonal Time–Frequency Space (OTFS) Modulation for 6G in Fractional Doppler Channels

open access: yesJournal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...

Tropospheric Propagation Effects Extracted From ADS‐B Messages

open access: yesEngineering 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 ...
