Abstract: A communication method of the SMF type for a network of nodes including a multicast group. The method includes the steps, performed by a first node, of: determining a set of respective multipoint relays; determining the nodes for which the first node is a multipoint relay; determining a routing table including identifiers of destination nodes and corresponding identifiers of next-hop nodes; receiving a multicast packet sent from a sending node, where the first node is a multipoint relay; checking if, for each node identifier of the multicast group, the entry in the routing table that includes a destination node identifier corresponding to the node identifier of the multicast group contains a next-hop node identifier that corresponds to the sending node, and if the counter contained in the multicast packet respects a relation with a limit; and determining whether to retransmit the multicast packet, on the basis of the outcome of the checking step.

Abstract: A method for estimating the noise of a two-photon entangled state, including generating pairs of photons; for each pair of photons, defining a first polarization measurement, associated with a first angle, and defining a second polarization measurement, associated with a second angle. The method includes generating a first string of polarization measurements and a first string of angles; generating a second string of polarization measurements and a second string of angles; generating a first uncorrelated substring, formed by the polarization measurements of the first string associated with angles that are different from the corresponding angles of the second string of angles; generating a second uncorrelated substring, formed by the polarization measurements of the second string associated with angles that are different from the corresponding angles of the first string of angles; and determining an estimate of the noise on the basis of the first and the second uncorrelated substrings.

Abstract: The invention relates to an IF receiver that is able to solve the image band problem and, in particular, to reject any interfering signals so as to ensure correct demodulation of a received useful signal without having to interrupt the reception service. The receiver comprises a monitoring branch configured to monitor interference experienced at a plurality of intermediate frequencies usable in reception and select the intermediate reception frequency from the intermediate frequencies usable in reception on the basis of the interference monitoring carried out. Moreover, the monitoring unit is configured to carry out real-time monitoring of interference experienced at the currently used intermediate reception frequency and also at the other intermediate frequencies usable in reception and change, in real time, the used intermediate reception frequency on the basis of the real-time interference monitoring.
