Method and system for multichannel point-to-point radio transmission with limitation of coupling losses

Abstract

The invention relates to a data transmission method, comprising the steps of: generating from a data stream to be transmitted, a plurality of frequency-domain digital sample streams, each digital sample stream modulating a respective subcarrier defining a respective subcarrier channel, converting the frequency-domain sample streams into temporal sample streams, by an inverse spectral transform, combining the temporal sample streams into a composite stream, frequency-shifting the composite stream using a digital oscillator at an intermediate frequency above 1 GHz, converting the shifted composite stream into an analog signal, frequency-shifting the analog signal to a carrier frequency above 2 GHz using an analog oscillator at a carrier frequency, filtering the analog signal to attenuate the carrier frequency, and transmitting the filtered signal via an antenna.
