Suppression of grating lobes for MMW sparse array setups [PDF]

open access: yesAdvances in Radio Science, 2011
For arrays the placement of the single elements determines the angular resolution and the unambiguity interval. The width of the total array determines the resolution capabilities.

Towards a Context-Free Machine Universal Grammar (CF-MUG) in Natural Language Processing

open access: yesIEEE Access, 2020
In natural language processing, semantic document exchange ensures unambiguity and shares the same meaning for documents sender and receiver cross different natural languages (e.g., English to Chinese), this difference makes the translation between ...

On Determinism and Unambiguity of Weighted Two-way Automata [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
In this paper, we first study the conversion of weighted two-way automata to one-way automata. We show that this conversion preserves the unambiguity but does not preserve the determinism.

On the ambiguity function for accelerating target in FMCW radar

open access: yesJournal of Telecommunications and Information Technology, 2023
In the paper, we are concerned with FMCWradar detection of an accelerating target, echo of which is buried in an additive white Gaussian noise. We derive and analyze three-dimensional generalized ambiguity function for target range, velocity and ...

Optimization of the Unambiguity of Cross-Correlated Ultrasonic Signals through Coded Excitation Sequences for Robust Time-of-Flight Measurements

open access: yesSignals, 2021
The cross-correlation function (CCF) is an established technique to calculate time-of-flight for ultrasonic signals. However, the quality of the CCF depends on the shape of the input signals. In many use cases, the CCF can exhibit secondary maxima in the
