    摘要: A method of receiving signals in a spread-spectrum telecommunications system with terrestrial repeaters, and a terminal for receiving, the terminal including two rake receivers (16, 18), each receiver having a set of demodulation channels (20-1, 20-n, 24-1, 24-n) and a combiner (22, 26). A third combiner (28) receives the signals provided by the combiners belonging to the two above-mentioned receivers. In this way, signals arriving from a diffuse system of terrestrial receivers and a complementary source can be received, in spite of the time differences between the different paths of the signals. The terminal can be used in a telecommunications system with numerous multiple paths.

    摘要: This invention concerns a terrestrial repeater (RF) dedicated to a hybrid communication network comprising a satellite for transmitting to terminals (and at least to the repeater) signals (SPI) in the form of a first modulated carrier with data to be transmitted, encoded by suing initial sequences of at least two pseudo-random codes, and spectrally spread with spreading codes each associated with a sequence. The repeater comprises: i) first processing means (MRP, MTB) for dispreading and demodulating the received signals so as to retrieve the encoded data which they represent for decoding them, and ii) second processing means (MTPi, APi) for re-encoding the retrieved data with one first part of the codes of the corresponding sequence to constitute first encoded data, and with at least a second part of the codes of the corresponding sequence, at least complementary to the first part, to constitute at least second encoded data, and to generate to the terminals, first signals (SP″), in the form of the first modulated carrier with the first encoded data and spectrally spread, at lest second signals (SP2) in the form of at least and second modulated carrier with the second encoded data and spectrally spread.
