suppression effect on the interference signal and can clearly see the outstanding useful
signal. It can be seen from Fig. 12.4 that the interference signal is further suppressed,
which greatly highlights the useful signal. From Fig. 12.5, it can be clearly seen that
all signals except useful ones have been greatly suppressed.
12.4 Conclusion
In this paper, the traditional kurtosis analysis method is improved, and the equal
time difference kurtosis analysis method is established according to the practical
application. Equal time difference kurtosis analysis is to calculate the kurtosis value of
