The sequencing of signal processing is used in numerical cellular radiotelephone communication to send digitized voice communication between a terminal and a base station by means of traffic frames (TF), each of which are made up of time intervals, the terminal having a time interval for transmission to the base station and a time interval for reception from the base station, the communication being made up of blocks (B) corresponding to groups of samples of speech, each block consisting of sub-blocks (SB) that are each transmitted during the corresponding time intervals of successive traffic frames and being characterized by the fact that, during each traffic frame (TF) a number of operations are carried out: + configuration processing (OP1, OP15), + processing of a receipt time interval (OP6), + processing of a broadcast time internal (OP13), - transmission block processing (OP11) is done during a specific traffic frame, the transmission frame, - reception block processing (OP7) is also done during a specific traffic frame, the reception frame.
La séquencement du traitement du signal s'applique dans le mode communication d'un système de radiotéléphone cellulaire numérique pour acheminer une communication de parole numérisée entre un terminal et une station de base au moyen de trames de trafic (TF) composées chacune d'intervalles de temps, le terminal disposant d'un intervalle de temps d'émission à destination de la station de base et d'un intervalle de temps de réception en provenance de la station de base, la communication étant composée de blocs (B) correspondant à des groupes d'échantillons de parole, chaque bloc étant formé de sous-blocs (SB) acheminés chacun durant les intervalles de temps correspondant de trames de trafic successives, et se caractérise en ce que, - durant chaque trame de trafic (TF) sont effectués : + un traitement de configuration (OP1, OP15) + le traitement d'un intervalle de temps de réception (OP6), + le traitement d'un intervalle de temps d'émission (OP13), - durant une trame de trafic particulière, la trame d'émission, est effectué de plus le traitement d'un bloc d'émission (OP11), - durant une trame de trafic particulière, la trame de réception, est effectué de plus le traitement d'un bloc de réception (OP7).
