TRANSMISSIONRECEPTION OF MICROWAVE SIGNALS BROADCAST BY A SATELLITE WITH AN INTERACTIVE RETURN CHANNEL USING A SPECTRAL BROADENING PROTOCOL

摘要

The present invention relates to a transceiver 1 for microwave radio signals, the apparatus comprising a transceiver 2 for transmission and reception, which is output from the conversion of radio signals received via a terrestrial or satellite link. Receiving means (4) capable of receiving an electrical signal as a forward link signal, a demodulator (21) capable of demodulating an electrical signal using a first modulation / demodulation protocol, and a spread spectrum different from said first protocol A modulator 5 for modulating an electrical signal using a second modulation / demodulation protocol, which is a protocol, and a signal demodulated by the demodulator 21, and an electrical signal modulated using a spread spectrum protocol. Means 23 for converting into a wireless signal that can be transmitted over the link. The apparatus also includes one or more boxes 11 including a modulator 14 for modulating the electrical signal using the first modulation / demodulation protocol, and a coaxial cable 10 connecting the transmitting and receiving unit to the box. Include.
