Patent ID: 7424068

Claim:
A method for decoding signals comprising symbols encoded on respective symbol intervals that modulate a carrier, comprising: performing a phase locking of a signal to be decoded to obtain a phase-locked signal which is present during the symbol intervals variations induced by disturbance affecting the signal to be decoded, wherein said step of performing a phase locking comprises comparing a phase of said signal to be decoded with a phase of a reference signal to obtain a respective resulting signal, subjecting said resulting signal to a decider to obtain a value of an estimated encoded symbol, and generating said reference signal as a signal comprising respective symbols encoded on given symbol intervals that modulate a given carrier, said given symbol intervals and said given carrier being homologous to said symbol interval and to said carrier of the signal to be decoded, respectively, so that a structure of a transmission code is repeated to enable decoding of the signal to be decoded; detecting a value of said phase-locked signal on at least one subinterval in each of the symbol intervals; and attributing to a decoded symbol corresponding to each of the symbol intervals a value obtained as a function of the value detected on said at least one subinterval.
