Application of kalman filters as a tool for phase and frequency demodulation of IQ signals

Frequency or phase modulated electrical signals arise in multiple applications in communication systems as well as in measurement setups such as interferometry / vibrometry, velocimetry etc. common demodulation techniques are often based on analog techniques (e.g. a PLL in the RF band) or - after mi...

More Information
Summary:Frequency or phase modulated electrical signals arise in multiple applications in communication systems as well as in measurement setups such as interferometry / vibrometry, velocimetry etc. common demodulation techniques are often based on analog techniques (e.g. a PLL in the RF band) or - after mixing into the base band and generating IQ signals - on digital signal processing algorithms.
