We are currently trying to determine the heart rate with a radar sensor. The phase of the signal has already been extracted and filtered. Now we want to improve the signal using an OMP algorithm in order to obtain a clear peak with an FFT.
We used the sklearn libary for the OrthogonalMatchingPursuit function. But we dont get the program to run. All examples online are for a signal with a fixed time and samples. How can we get it to run with our live signal?
our used code: The sensor data we get are in self.phase_unwrap

thanks for your help

we also dont really got the concept of the OMP algorythm, especally the usage of the dictionary.
