I am trying to compare several PSD methods to determine the most suitable method for my application. Does anyone know a good approach to start with? I am relatively new to this field of topic.

I could possibly compare the results of the psd methods, the computational complexity and the resolution of the results.

How to compare PSD methods?

Same way you deal with any type of engineering problem of this sort:

  1. Write down requirements of your application. What are the priorities, sensitivities and minimum quantitative requirements/thresholds.?
  2. Write down the properties, features and parameter space of the different PSD approaches that you have found.
  3. Compare #1 and #2, find the PSD method and parameters that meets your requirements the best and/or has the best set of tradeoffs.
