Abstract: A method for determining a phase bias in the signal transmitted by at least one of the radiating elements of an active antenna on the ground emitting signals into space using a space-division multiple access SDMA method, implementing a step, for each reference receiver, of comparing, to a threshold, the difference between the value of a measurement of the power received by each reference receiver and the sum, out of the radiating elements of the subset beamforming in the direction of the reference receiver, of the differences between the equivalent isotropically radiated power in the direction of the reference receiver and the free-space path loss of each radiating element of the subset.

Abstract: A method is provided for demodulating a signal carrying a message transmitted by a terrestrial beacon, executed by a system comprising a constellation of satellites suitable for detecting said signal and for repeating it towards receiving stations on the ground, and an analysis module suitable for receiving signals from said stations. Each receiving station transmits the signals that it receives from the satellite to the analysis module, said module realigning said signals in frequency and/or in time relative to one another, combining the realigned signals to generate a synthetic signal having an enhanced signal-to-noise ratio, and determining the content of said message and/or the modulation parameters of said synthetic signal. The method applies notably to the accurate and reliable location of distress beacons by a satellite system.

Abstract: An integrated radio communication system with ordered hierarchical cellular coverage comprises a first system and a second system, the coverage of the second system covered by the coverage of the first system, and a set of dual-mode terminals that can selectively use the first system or the second system. The first and second systems are configured to simultaneously share a common portion Bc of a first band B1 of frequencies respectively on a first uplink and a second uplink, and respectively manage first transmission resources and corresponding second transmission resources. The second radio communication system of lower level N2 is free to manage its second transmission resources without any coordination constraint with respect to the first system of higher level N1, whereas the first system of higher level is configured to not disturb the second system in the common frequency band portion. The first system is configured to transmit data packets on a first uplink random access contention channel and to manage its first resources optimally in terms of transmission capacity of the channel as a function of the measurement of the occupancy of the second radio resources currently used by the second system and of the first resources currently used by the first system.
