Abstract (en)
[origin: WO9600472A1] A method for estimating residual phase error in data samples (Zk) of a demodulated digital signal, comprising the steps of making a hard decision (31) concerning the value of each sample by combining each sample with the likeliest data element among a constellation of data elements forming a modulation alphabet; determining (32) a phase shift between each sample and the related data element; and estimating (33, 34) information representing said residual phase error on the basis of the phase shift corresponding to at least two samples.
