Abstract:
1. A terrestrial repeater (RT) for a hybrid communication network, including at least one communication satellite (SAT) adapted to transmit to communication terminals (UE) and at least to said repeater signals in the form of a first carrier modulated with principal data to be transmitted, encoded by means of initial sequences of at least two mutually orthogonal pseudo-random codes each associated with a physical transmission channel, and spread spectrally by means of spreading codes each associated with a sequence, the terrestrial repeater comprising i) first processor means (MRP, MTB) adapted, on reception of said signals, to despread said signals and to demodulate said signals to recover the encoded principal data that said signals represent in order to decode said principal data, and ii) second processor means (MTPi, API) adapted to re-encode said recovered principal data with a first portion of the codes of said corresponding sequence to constitute first encoded principal data and, with at least one second portion of the codes of said corresponding sequence, at least complementary to said first portion, to constitute at least second encoded principal data, and to generate for said terminals (UE), first signals in the form of said first carrier modulated with said spectrally spread first encoded principal data and, at least second signals in the form of at least one second carrier modulated with said spectrally spread second encoded principal data.
