Signal Processing
Semantic TS works on signal processing of real signals
(obtained from measurements) or simulated ones (generated) . This involves the following abilities
:
 | Writing of programs for signal prediction and simulation (spectrum,
moments) |
| Feasibility study and application of new tools (adapted
filtering, time-frequency analysis, non linear, stochastic...) of signal
processing to improve existing projects (localization, telemetry...) |
| Extension of the use of these signal processing techniques
to inverse problems (localization , tomography...) |
Semantic TS
has developed a specific signal processing software, named
TACSI. This code contains
the following modulus :
|
Signal processing (Fourier transform, Gabor transform,…; cross-correlation, beam forming, adapted filtering,
statistical analysis, …) |
|
Signal generation (window, sinus, MF, PSK) |
|
Acquisition and treatment |
|
Visualization modulus (graphic library ) |
| useful tools like temporal shift,
export/import, saving functions, … |
and has worked on theses projects:
| Signal processing for LEXIPHONE devoted to
dyslexic therapy |
| Satellite image processing : improvement of
images resolution |
