A new demodulation procedure for a class of multiplexed signals
Résumé
This paper introduces a set of estimators for a wide class of multiplexed signal. The signals of interest are decomposed on independent periodic signals with a shared frequency. This latter set of signals is as general as possible; that is, not necessarily orthogonal or sinusoidal. By an adequate linear combination of low-pass filters, we extract each of the components of the multiplexed signal with an arbitrary accuracy. Applications of this demodulation procedure include sensorless control of electrical machines using signal injection with the extraction of the ripple.
