The two dimensional Mazo limit [PDF]

open access: yesProceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
Faster than Nyquist (FTN) signaling is extended. We send FTN pulse trains that overlap in both time and frequency; this is called two dimensional Mazo signaling. The minimum time and frequency separation that achieves dmin 2 = 2 for root raised cosine pulses is found. Two dimensional signaling is more bandwidth efficient than one dimensional.

Hexagonal Multicarrier Faster-Than-Nyquist Signaling

open access: yesIEEE Access, 2017
Multicarrier faster-than-Nyquist (MFTN) signaling is a spectral efficient modulation scheme for future communication systems. In MFTN signaling, the intersymbol interference (ISI) and intercarrier interference (ICI) are introduced intentionally by the ...

Low-Complexity Detection of High-Order QAM Faster-Than-Nyquist Signaling

open access: yesIEEE Access, 2017
Faster-than-Nyquist (FTN) signaling is a promising non-orthogonal transmission technique to considerably improve the spectral efficiency. This paper presents the first attempt in the literature to estimate the transmit data symbols of any high-order ...

A Very Low Complexity Successive Symbol-by-Symbol Sequence Estimator for Faster-Than-Nyquist Signaling

open access: yesIEEE Access, 2017
In this paper, we investigate the sequence estimation problem of binary and quadrature phase shift keying faster-than-Nyquist (FTN) signaling and propose two novel low-complexity sequence estimation techniques based on concepts of successive interference

Investigation into heavy metal concentration by the gravel roadsides / Sunkiųjų metalų koncentracijų žvyrkelių pakelių dirvožemiuose vertinimas / Оценка концентр аций тяжелых металлов в почве обочин гравийных дорог

open access: yesJournal of Environmental Engineering and Landscape Management, 2011
Vehicles release large amounts of heavy metals to the environment. There have been done a lot of investigations analysing the distribution of heavy metals in soils near intensive regional roads. However, there is lack of investigations into the impact of

A Hybrid Network Integrating MHSA and 1D CNN–Bi-LSTM for Interference Mitigation in Faster-than-Nyquist MIMO Optical Wireless Communications

open access: yesPhotonics
To mitigate inter-symbol interference (ISI) caused by Faster-than-Nyquist (FTN) technology in a multiple input multiple output (MIMO) optical wireless communication (OWC) system, we propose an ISI cancellation algorithm that combines multi-head self ...

On the existence of the Mazo-limit on MIMO channels

IEEE Transactions on Wireless Communications, 2009
Mazo, in 1975, showed that the signaling rate of a linear modulation can be significantly higher than the maximum rate for orthogonal signaling without any loss of minimum square Euclidean distance. In subsequent literature the highest such rate is referred to as the Mazo-limit.
