Abstract: A method for correlating events is described. The method includes receiving a plurality of data streams, each of the streams having been emitted by an emitting source and including data representative of an event acquired by the source at the time of the emission and a marker representative of the backscattering of the data stream by a transmitting device. The method also includes determining a spatial and/or temporal correlation of the events from the markers.

Abstract: A process for generating at least one backscattering zone, by at least one transmitter device and to at least one receiver device, of an ambient radio signal emitted by at least one source; and a process for generating at least one reception zone, by the receiver device, of the backscattered ambient signal. The process for includes: determining an emission constraint, when it is respected by the source, for generating at least one backscattering zone in which the received electromagnetic power is greater than a determined threshold, called “backscattering threshold”, and/or generating at least one reception zone in which the received electromagnetic power is less than a determined threshold, called “reception threshold”; and transmitting, by the source, with respect to the emission constraint.

Abstract: A method of transmitting, by a first device, pilot symbols to allow a second device to estimate a transmission channel between the first and second devices. The first device has a first antenna that is active in transmission and a second antenna that is passive in transmission. The method includes: transmitting, by the first active antenna, a signal conveying pilot symbols associated with the first active antenna, and during which the second passive antenna is set to a transparency impedance to obtain a level of signal backscattered by the second passive antenna less than a first threshold; and transmitting by the first active antenna a signal conveying pilot symbols associated with the second passive antenna, and during which the second passive antenna is set to a scattering impedance to obtain a level of signal backscattered by the second passive antenna greater than a second threshold greater than the first threshold.

Abstract: An iterative precoding method for a TDD data transmission system includes a transmitter provided with N transmit antenna(s) (N≧1), and a receiver provided with M receive antennas (M≧2). A series of precoders Ln (n≧0) is defined. Each iteration includes: the transmitter takes account of a predetermined value n=n0 if it is the first iteration, or else a value of n obtained during the preceding iteration; the transmitter sends a triplet of pilot signals precoded with the precoders Ln, Ln+1, and Ln+2 to the receiver; the receiver estimates the triplet (Tn, Tn+1, Tn+2) of total data rates that can be achieved corresponding respectively to (Ln, Ln+1, Ln+2), and deduces therefrom the value of a control command p; the receiver sends a signaling message specifying the value of the control command p; and on receiving the signaling message, the transmitter updates the value of n, by replacing it with the value (n+p).

Abstract: A wireless communication device having a full-duplex architecture is described, the device comprising phase shifters integrated into transmitting chains and receiving chains, respectively, which are connected to basic antennae. Each transmitting/receiving chain is associated with a receiving/transmitting chain so as to form a pair of chains, with a connection circuit arranged between the chains of each pair. The device also includes at least one control module configured to control switching means and to activate/deactivate analogue means and digital means for cancelling interference and all or some of the transmitting/receiving chains so that the device is able to alternate between at least two different modes: a first full-duplex transmitting/receiving mode, and a second mode in which the device is able to reflect one or more transmission beams.

Abstract: A wireless communication device is described, having an analogue-digital hybrid architecture comprising passive phase shifters. The device includes a control module configured to control means for switching the communication device, such that the device is capable of alternating between three separate modes: a first/second mode in which each passive phase shifter is integrated into a transmission/reception chain, and a third mode in which each passive phase shifter is integrated into a transmission line. The transmission line includes a first portion connecting a first port of the passive phase shifter to the elementary antenna to which it can also be connected in the first/second modes and configured such that substantially all the electromagnetic energy associated with a transmission beam received by the elementary antenna is transmitted to the passive phase shifter, and also includes a second portion connecting the second port of the passive phase shifter to an impedance configured to reflect the electromagnetic energy.

Abstract: A method is described for determining a graph modelling a zone comprising at least one transmitting device for backscattering an ambient signal, emitted by a transmitting device, towards a receiving device (for detection by said receiving device. The method includes obtaining at least one coverage area of said zone, said at least one coverage area having been determined for a location of said zone and corresponding to a datum identifying the transmitting device or devices detected by the receiving device when the transmitting device occupies said location. The method also includes determining a graph of which at least one vertex consists of said at least one coverage area, two vertices of said graph being connected by an edge if the coverage areas relating to said two vertices comprise at least one transmitting device detected in common.
