A signal is filtered by multiplying its Fourier transform by the Fourier transform of a reference sequence to which the filtering is to be matched. The reference sequence (e.g. a Golay sequence pair) is defined as an iterative combination of shorter sequences and its Fourier transform is generated by an iterative process of combining the Fourier transforms of a shorter starting sequence.
Selon l'invention, un signal est filtré par multiplication de sa transformée de Fourier par la transformée de Fourier d'une séquence de référence sur laquelle le filtrage doit être adaptée. La séquence de référence (par exemple, une paire de séquences de Golay) est définie en tant que combinaison itérative de séquences plus courtes et sa transformée de Fourier est générée selon un processus itératif de combinaison des transformées de Fourier d'une séquence de départ plus courte.
