Abstract (en)
[origin: EP3672275A1] Provided are a method and system for continuously extracting target interference signals from selected signals, and a storage medium. The method comprises: collecting a two-channel or multi-channel input signal, each channel of the input signal containing a target interference signal; increasing independence of the input signal; calculating to obtain a resulting coefficient matrix after the independence of the input signal has been increased; synchronizing each pair or each group of input signals; separating the synchronized input signals into the target interference signal and a desired signal; and intelligently selecting an output signal.
