A method for decoding signals with encoded symbols over a symbol interval
that modulate a carrier. The method includes phase locking the signal to
be decoded to obtain a phase-locked signal. The value assumed by the
phase-locked signal on at least one subinterval in each symbol interval
is detected. The method continues with attributing to the decoded symbol
corresponding to each symbol interval a value that is a function of the
value detected the subinterval. The subinterval in question can be a
single subinterval located at the end of the symbol interval.
Alternatively, the value assumed by the phase-locked signal on a
plurality of subintervals in each symbol interval is detected, and a
respective majority value of said phase-locked signal within said
plurality of subintervals is identified. A value determined on the basis
of the majority value is attributed to the decoded symbol corresponding
to each symbol interval.
