Indeed, when using the integral square method to calculate the leading edge of the signal, this leading edge is not the real time delay of the signal relative to the sampling point, however, more accurate delay estimation is very critical. .
In fact, the square integral method to calculate the signal front, this front is not the signal relative to the first sampling point real time delay, however on the time delay estimation is able to accurately is very important..
In fact, the use of square integral method to calculate when the leading edge of signal, the frontier is not true time delay of signal relative to the sample start point, but is capable of more precise time delay estimation is crucial ...
