A METHOD OF PACKET MODE DIGITAL COMMUNICATION OVER A TRANSMISSION CHANNEL SHARED BY A PLURALITY OF USERS

摘要

The method involves generating two replicas for each data packet to be transmitted. The replicas are emitted through a transmission channel, where the replicas are separated by lags and/or random frequency. Signaling information is inserted in each replica permitting to locate temporally and/or in frequency the other replicas of the same packet even if the packet or replicas are corrupted by collisions. A binary acquisition sequence is generated and inserted in each packet. Independent claims are also included for the following: (1) a method for recovery with the reception of data packets transmitted through a transmission channel (2) a data packet transmission equipment (3) an equipment for recovery with the reception of data packets transmitted through the transmission channel.
