Installation for the transmission/reception of radio signals

摘要

A transmitting/receiving installation of microwave radio signals including a transmitting/receiving unit. The unit includes a receiving module to receive electrical signals, known as terrestrial electrical signals, issued from the transformation of radio signals received terrestrially, a module to transform the electrical signals modulated according to a spread spectrum protocol, known as satellite electrical signals, into radio signals able to be transmitted by satellite, a transmitter to transmit to a satellite of the microwave radio signals obtained after transformation of the satellite electrical signals and an amplifier to amplify the satellite electrical signals. The installation includes a box including a modulator of electrical signals according to a spread spectrum protocol and a coaxial cable connecting the transmitting/receiving unit and the box.

1. A transmitting/receiving installation for microwave radio signals comprising:
a transmitting/receiving unit comprising:
a receiver configured to receive terrestrial electrical signals issued from a transformation of radio signals received terrestrially;a frequency shifter configured to transform satellite electrical signals modulated according to a spread spectrum protocol into radio signals capable of being transmitted to a satellite;a transmitter configured to transmit to a satellite microwave radio signals obtained after the transformation of said satellite electrical signals and is further configured to transmit said microwave radio signals to a ground station;an amplifier configured to amplify said satellite electrical signals; a box including an electrical signal modulator according to the spread spectrum protocol, the electrical signal modulator being further configured and arranged to modulate signals in an intermediate frequency band and wherein the frequency shifter is further configured and arranged to the transform modulated signals in said intermediate frequency band to a transmitting frequency band;
the box further comprising:
a demultiplexer configured and arranged to extract from terrestrial electrical signals, signaling information for establishing transmission parameters to be used by the transmitting/receiving unit;a clock signal demultiplexer configured to extract a clock signal from an electrical signal and a transmitter to transmit said clock signal to said frequency shifter such that the frequency of said clock signal is able to be added to the frequencies of said intermediate frequency band; a coaxial cable configured to connect the transmitting/receiving unit and the box, the coaxial cable adapted to:
convey said terrestrial electrical signals from said transmitting/receiving unit to said box, andconvey electrical signals issued from said modulator according to the spread spectrum protocol from said box to said transmitting/receiving unit.
