摘要： The invention relates to such an access point (10) comprising:
a determination module (12) for determining a signal distortion caused by the own hardware impairments thereof,
a transmission module (14), via a fronthaul link comprising a plurality of access points in series, ordered along a predetermined direction of travel to the central unit of a base station, of said distortion to another access point, or to the central unit, following it within said fronthaul bond; and/or
a reception module (16) for receiving and taking into account said distortion of an access point preceding it within said fronthaul link, so as to determine the local precoding filters of said access point configured to cancel said distortion of said access point preceding it.-

摘要： A method for imaging an area of interest on the ground uses a georadar equipped with a plurality of transmitter antennas and a plurality of receiver antennas. A bistatic RCS matrix is calculated at each point of a grid based on the matrix representing the MIMO channel modelling the propagation and the reflection in the area of interest, a matrix representing the losses along the propagation paths of the channel, and a phase-shifter matrix representing the delays on these same propagation paths. The bistatic RCS matrices relating to discrete frequencies belonging to the same coherence sub-band are summed and the elements of the matrices thus obtained are then summed incoherently to provide an overall backscatter coefficient for each point of the grid. Afterwards, an image representing this backscatter coefficient at each point of the grid is generated. A method for detecting a ground target-uses the same principle.

摘要： A method for fabricating an asymmetric SOT-MRAM memory cell unit, the memory cell unit including a conductor track and a pad, arranged on the conductor track and including at least one first magnetic region with free magnetization. The method further includes producing a stack of a plurality of extended layers, including at least one first extended magnetic layer; depositing a mask on an upper surface of the stack; and defining the first magnetic region in the first extended magnetic layer though ion irradiation of the upper surface of the stack carrying the mask, the parameters of the ion irradiation being adapted so as to modify magnetic properties of the material forming the first magnetic layer.

摘要： The use of a synergistic mixture of extractants for extracting at least one rare earth element from an aqueous medium comprising phosphoric acid. The mixture comprises: —a first extractant of formula (I):
wherein R1 and R2, which are identical or different, represent a linear or branched, saturated or unsaturated hydrocarbon group, comprising from 6 to 12 carbon atoms, or a phenyl group optionally substituted by a linear or branched, saturated or unsaturated hydrocarbon group, comprising from 1 to 10 carbon atoms; and—a second extractant of formula (II):
in which R3 represents a linear or branched alkyl group, comprising from 6 to 12 carbon atoms.
Use of the synergistic mixture in the treatment of phosphate minerals with a view to recovering the rare earth elements contained in the minerals.-
