Title
(EN) METHOD FOR TRANSMITTING DATA OVER A MULTIPLE-ACCESS COMMUNICATION CHANNEL
(FR) PROCÉDÉ DE TRANSMISSION DE DONNÉES SUR UNE VOIE DE COMMUNICATION À ACCÈS MULTIPLE
Abstract
(EN) A first aspect of the invention relates to the transmission (100) of data over a multiple-access communication channel, the communication channel being divided into slots and/or frequencies. A message to be transmitted is transmitted in a number, hereinafter referred to as n, of packets distributed over n randomly selected slots and/or frequencies, each packet including a signaling section indicating the slots and/or frequencies of the n-1 other packets in which the message is transmitted. The message to be transmitted is encoded using a correction code so as to form a codeword (104), the thus-formed codeword is divided into n portions (106) that are distributed over the n packets (114), and the signaling sections are encoded separately from the message using a correction code (112). Another aspect of the invention relates to receiving data transmitted in the described manner.
(FR) Un premier aspect de l'invention concerne la transmission (100) de données sur une voie de communication à accès multiple, la voie de communication étant segmentée en créneaux et/ou en fréquences. Un message à transmettre est transmis en un nombre, ci-après noté n, de paquets répartis sur n créneaux et/ou fréquences sélectionnés de manière aléatoire, chaque paquet comprenant une section de signalisation indiquant les créneaux et/ou fréquences des n-1 autres paquets dans lesquels le message est transmis. Le message à transmettre est encodé à l'aide d'un code correcteur pour former un mot de code (104), le mot de code ainsi formé est divisé en n parties (106) qui sont réparties sur les n paquets (114) et les sections de signalisation sont encodées, séparément du message, à l'aide d'un code correcteur (112). Un autre aspect de l'invention concerne la réception de données transmises de la façon décrite.
