miss value

Signal decomposition is very useful to me, but I want to know what to do if my signal has missing values?

@J-Shuo ：
This is a very valuable question ✨. During the signal sampling process, due to the influence of external noise or the sensitivity of the device itself, the sampled signal may have some missing values. Unfortunately, all the data-driven signal decomposition algorithms currently cannot handle signals with missing values.
However, handling missing values ​​is indeed a very important thing. For this reason, I will further investigate what methods can be used to handle missing values ​​in signal processing and time series analysis. In my future work, I will provide functions to fill missing values ​​for signals to overcome this problem.
