Research on Signal Separation of Same Frequency Based on Array Antenna

The same frequency signal separation of array antenna has very important theoretical significance and practical value, and has important value in some fields of signal processing. Due to the disadvantage that FastICA algorithm based on negative entropy is sensitive to the initial value selection, this paper improves the disadvantage of FastICA algorithm based on negative entropy, and gives the FastICA algorithm and the experimental comparison of the improved FastICA algorithm through MATLAB simulation. The simulation results show that, for the separation of mixed signals with the same frequency, The improved FastICA algorithm can achieve a better separation effect.
