摘要： A device (D1) is dedicated to the processing of signals to be transmitted by waves, within a communication terminal (T). This device (D1) comprises i) memory means (M1) for temporarily storing a sequence of digital samples of an analogue input signal according to a first sampling frequency and in a manner synchronized with respect to starts of periodic time slots, and ii) digital/analogue conversion means (CV2) for generating, during each time slot and according to a second sampling frequency equal to N times the first sampling frequency, with N an integer strictly greater than 1, an analogue output signal, to be transmitted, representative of N repetitions of the sequence of digital samples that is stored in the memory means (M1) during the time slot concerned, so as to output the analogue signal according to a symbol rate equal to N times a reference symbol rate.

摘要： A device (D) is dedicated to the processing of data by spread spectrum coding for a multi-beam communication satellite (S), each beam (B1-B6) of which is associated with a terrestrial cell (C1-C6) contained in a satellite coverage zone (ZC). This device (D) comprises coding means (MC) charged i) with associating, on the one hand, sets of pseudo-spreading codes (J1-J4), differing pairwise, with adjacent cells of the zone (ZC) and with signalling channels common to the collection of cells (C1-C6) of this zone (ZC), and on the other hand, identical sets of pseudo-spreading codes with non-adjacent cells of the zone, the sets (J1-J4) being chosen from among sets resulting from the subdivision of a collection of pseudo-spreading codes, and ii) when data have to be broadcast in a cell (C1) and/or common information data have to be broadcast in the collection of cells, with modulating pseudo-spreading codes belonging to the set (J1) associated with this cell (C1) with the data to be broadcast, then with modulating a carrier, whose frequency (f) is the same for all the beams (B1-B6) of the satellite (S), with the modulated pseudo-spreading codes so that the modulated carrier is broadcast towards the cell (C1) or the collection of cells (C1-C6) by means of the associated beam (B1).
