Time domain averaging based on phase compensations
Bao Xizhong · Applied Acoustics · 2011
This paper introduces a method of time domain averaging,based on phase compensating.This method eliminates the effect to the performance as a result of non integral times of signal periods truncating.Without the apriori information of the signal frequency and higher sampling frequency,it can realize the time domain averaging having no phase error through searching the frequencies,which is concerned with the length of the truncated signal only.The simulation results show that the signal gain is consistent with that of integral times of the period truncating.
