Claim 1:
2. The method of claim 1, wherein performing the processes on the current sampling point and the groups of sampling points to obtain the data of arguments of complex numbers corresponding to the preset intervals comprises performing following processes on the current sampling point and the groups of sampling points:
performing a conjugate multiplication, an amplitude multiplication and a phase subtraction on the current sampling point and the groups of sampling points, and then performing a M-th power operation to obtain a M-th power correlation value, with M being an integer greater than 2;
adding M-th power correlation values every N beats to obtain accumulation data, with N being an integer greater than 2;
filtering the accumulation data to obtain filtered data; and
obtaining the data of arguments of complex numbers corresponding to the preset intervals according to the filtered data and the preset intervals.
