Abstract
Un récepteur (900) met en application un procédé (1100) servant à identifier un signal de communication codé (301) à partir de signaux reçus de communication codés (303, 305). Le récepteur (900) comprend un dispositif mémoire (905) et un processeur (907). Le dispositif mémoire (905) mémorise des informations contenues dans les signaux reçus de communication codés (303, 305) pendant des intervalles multiples de modulation en temps symbolique (210), afin de produire des informations mémorisées. Le processeur (907) recherche ensuite les informations mémorisées, afin d'identifier le signal de communication codé (301).
