METHOD FOR DETERMINING THE SAMPLING PHASE AND METHOD FOR SYNCHRONISATION WORD DETECTION USING THE PHASE DETECTION METHOD

摘要

The invention concerns a method for determining the sampling phase of a signal modulated by digital modulation, said method comprising steps which consist in: oversampling factor m of the co-ordinates of L consecutive symbols, converting the oversampled co-ordinates of L symbols into angular values, retracing the angular values on one point of the modulation constellation, estimating the noise of the angular values, for each oversampling phase, with respect to said point and selecting the sampling phase with the least noise. The invention also concerns a method for detecting a synchronisation word.
