Abstract:
1. Process for radiomobile communication of the time division multiple access type, in which timeslots are allocated to several users for transmission and reception of radioelectric signals, and in which: on transmission, data symbols and reference symbols are created in each allocated timeslot, a radioelectric signal containing these data symbols and reference symbols is transmitted, this signal being sent along a multi-path radiomobile channel, on reception, matched filtering is applied to the received signal, the filtered signal is sampled at the rate of the symbols, an estimate of the radiomobile channel is made, the samples are processed using this channel estimate and data symbols specific to the allocated timeslot are restored, this process being characterized in that: on transmission, several reference sequences possessing appropriate time correlation properties are built up for each allocated timeslot, and these sequences are distributed in each timeslot, on reception:
