    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: A control device for controlling the operation of a wireless communication device is described. The wireless communication device includes an antenna, a front-end module configured for transmitting and receiving signals according to a time-division multiplexing scheme, and switching means which can switch at least one transmission or reception chain of said front-end module between first and second modes in which the processing chain presents different impedances to the antenna. The control device can be integrated in the communication device and includes a control module to control the switching means so that the processing chain alternates between said first and second modes so that the communication device backscatters an ambient signal.

    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.
