Abstract
A transmission/reception installation for microwave radio signals, including a unit for transmission/reception including a receiver for receiving the electric signals from the conversion of radio signals received via a terrestrial or satellite link, referred to as forward-link signals, a demodulator for demodulating the electric signals using a first modulation/demodulation protocol, a modulator for modulating electric signals using a second modulation/demodulation protocol that is different than the first protocol, the second protocol being a spread-spectrum protocol, the modulator modulating the signals demodulated by the demodulator, and a converter for converting the electric signals modulated using a spread-spectrum protocol into radio signals that can be transmitted via a satellite link. The installation also includes one or more boxes including a modulator for modulating the electric signals using the first modulation/demodulation protocol, and a coaxial cable connecting the unit for transmission/reception to the boxes.
