Abstract: A transmission system includes: an optical transmission module capable of modulating a first digital radio signal in order to obtain a first optical signal; an optical reception module capable of receiving a second optical signal and demodulating same in order to obtain a demodulated radio signal; and a digitizing module capable of digitizing the demodulated radio signal in order to obtain a second digital radio signal. The transmission module includes: a module for adding a first management signal to the first digital radio signal, the rate of the first management signal being less than that of the first digital radio signal. The optical digitizing module includes an extraction module capable of extracting a second management signal from the demodulated radio signal, the rate of the second management signal being less than that of the second digital radio signal.

Abstract: A method for receiving an uplink reference signal sent by a mobile terminal to a network entity through a radio unit connected to an antenna, and used to geolocate the mobile terminal. The method is implemented by the network entity and includes: recording, by way of time of arrival of the reference signal, a time obtained by adding a delay, called a waiting delay, to the time at which the reference signal was sent by the radio unit, the waiting delay being larger in value than a transmit path time of a comparison signal, between the radio unit and the network entity; and sending a message to a geolocation server, including information relating to the recorded time of arrival.

Abstract: A device for coherent detection of data transported in an optical incoming useful signal. The device includes: a first incoming single-mode optical fibre, injecting the incoming useful signal; a second incoming single-mode optical fibre, injecting an optical signal of optical frequency substantially equal to that of the incoming useful signal, referred to as an oscillation signal, a signal mixer in which one of the signals from the first or second fibre is separated into two signals having orthogonal polarisations, and where the other one of the signals from the first or second fibre is mixed with the two separate signals, producing a mixed signal; a detector of the transported data present in the mixed signal; and an amplitude modulator configured to modulate the oscillation signal before it enters the mixer, the modulation pattern having repetitive pulses of the same interval as a symbol time of the incoming useful signal.

Abstract: A method for transmitting a downlink reference signal from a network entity to a mobile terminal via a radio unit connected to an antenna, used to geolocate the mobile terminal. The method is implemented by the radio unit and includes: receiving the reference signal from the network entity and destined for the mobile terminal; and transmitting the reference signal to the mobile terminal upon expiry of a delay period with respect to the transmission time of the reference signal by the network entity. The delay period has a value greater than a transmission travel time of a comparison signal between the network entity and the radio unit.
