ABSTRACT:
Method for determining the sampling phase of a signal modulated by digital modulation, is described. The method includes oversampling by factor m, the coordinates of L consecutive symbols. The oversampled coordinates of the L symbols are then converted into angular values. The angular values are folded over onto a point of the constellation of the modulation. The noise in the angular values is estimated for each oversampling phase, with respect to the point, and the oversampling phase exhibiting the lowest noise is selected. The subject of the invention is also a synchronization word detection process.
