    Abstract: A method is provided for transmitting data between a transmitter having M>=1 transmit antenna(s), and one or more receivers having a total of N>=2 receive antennas. In the method, the data are transmitted using OFDM/OQAM modulation having L>=1 subcarriers. The transmitted data are pre-encoded using a pre-encoding matrix, the size of which is M s N and which is dependent on a zero-forcing matrix and on a spatial multiplexing matrix.

    Abstract: A method establishing a quality indicator of a radio transmission channel in a first cell of a cellular network using a plurality of orthogonal frequency-division multiplexed subcarriers for transmitting data. A first transmitter located in the first cell transmits a reference control signal including a total-load control signal modulating one or more of the orthogonal subcarriers, during one or more first symbol times dedicated to transmission of symbols other than data symbols, and a useful-load control signal modulating one or more orthogonal subcarriers during at least one second symbol time dedicated to transmission of data symbols. A transmitter located in an adjacent cell transmits an interfering control signal modulating, during the first symbol time(s). The quality indicator is determined according to a measured quality indicator of the channel under the useful load and a measured quality indicator of the channel under the total load.

    Abstract: A method for configuring a transmitter device (TX) equipped with a plurality of antenna elements is described, the method making it possible both to adjust the electric field of beam F_1 so that the regulatory constraint is observed and to improve the rate received by a receiver device in the case of the signal following path P_2, by ensuring that the electric field of beam F_2 is equal to that of beam F_1, while still observing the regulatory constraint. In other words, the electric field of beams F_1 and F_2 is identical and maximized while still observing the regulatory constraint. As a result, the operation criterion is improved.

    Abstract: A method for selection by an ambient backscatter system including a source as well as transmitting and receiving devices, the source being associated with a precoder for focusing signals towards the devices. Furthermore, the method includes, for a plurality of values ϕ_1, . . . , ϕ_N: a phase-shift, by the source, of one of the components of the precoder according to the value ϕ_i, so as to obtain a precoder Q_i; an emission, by the source, using the precoder Q_i; an acquisition, by the receiving device, of power measurements during non-backscattering and backscattering states, a determination, by the receiving device, of a value D1_i representative of a power deviation between the measurements. The method also includes a selection, by the receiving device, of a maximum value among the values D1_1, . . . , D1_N.

    Abstract: A method for transmitting a message by ambient scattering. The method is implemented by a transmitting device in response to the transmitting device changing from a first state in which the transmitting device is deprived from illumination to a second state in which the transmitting device is illuminated by at least one light source. The method includes: obtaining an amount of electrical energy stored from light energy; comparing the amount of electrical energy stored with a given threshold, the threshold representing an electrical energy quantity sufficient to allow transmission of a message by ambient scattering; and in response to the threshold being overrun, transmitting a message called “information message”, representative of the threshold overrun, the transmission being implemented by using the stored electrical energy.

    Abstract: A method for controlling the backscattering of an ambient signal emitted by an emitter device is described. The method is implemented by a transmitter device configured to backscatter the ambient signal and includes acquiring a measurement of power received from the emitter device, and evaluating a criterion consisting of at least checking whether a distance, counted from a position occupied by the transmitter device during the acquiring of the current measurement and in which a given reception quality value is attained for a signal obtained by backscattering the ambient signal, is in a given interval, where the distance of coverage being defined as a function of the measurement and the value. The ambient signal is backscattered only if the criterion is met.

    Abstract: A method for monitoring objects, the objects including, respectively, tags that backscatter ambient signals. The method is implemented by a receiver device and includes: receiving a first backscattered signal originating from a first object, the first backscattered signal corresponding to an ambient signal and including a message having an identification datum relating to the first object; and determining the desired presence or the undesired presence of the first object in a geographical area as a function of the identification datum relating to the first object. Use for systems for monitoring objects, for example to detect proximity between objects that should not be close to one another.

    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.
