Abstract
A multiple frequency time division multiple access digital telecommunication system, in particular a transparent satellite telecommunication system, includes terminals and a base station. Calls can be effected in star mode, via the base station, or in meshed mode, directly between the terminals, which are divided into two groups. The frequency band allocated to the system is divided into two parts, comprising a first part for sending by the first group and a second part for sending by the second group. Each part of the frequency band is divided into two sub-bands. The central sub-bands are used for meshed sending, the end sub-bands are used for star sending, and the two central sub-bands are also used for meshed reception by both groups of terminals.
