ABSTRACT:
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.
