Abstract: The invention discloses an antenna arrangement and a method of designing the same, the antenna arrangement being tuned to radiate in a plurality of bands. The antenna arrangement comprises a first conductive element which has a compact linear 2D or 3D form factor. It also comprises leaves attached to the first conductive element, the position, dimension, form factor and orientation of which are defined based on their impact on frequency shifts of the fundamental and harmonic modes, so that the antenna arrangement radiates at a plurality of predefined frequencies. The design method uses maps of hot areas where the sensitivity to the parameters defined for the leaves is maximal. Advantageously, the design method is performed in a manner which uses an orthogonality of the impacts of the parameters of the leaves vis-à-vis the different radiating modes. The antenna arrangement is compact and well adapted to applications to the IoT and consumer communication devices.

Abstract: An encoder architecture for UF-OFDM is provided, in which samples are first processed sub-band wise, and then resorted for sub-carrier-wise processing. The sub-carrier processing may comprise separate processing for the two extremity parts of the base band signal corresponding to the transient state of the UF-OFDM data stream and for a core part of the base band signal corresponding to the non-transient state of the UF-OFDM data stream, and then concatenated to obtain a UF-OFDM data stream. In certain embodiments a first extremity part of the base band signal corresponding to the transient state of the UF-OFDM data stream is calculated directly, and the other extremity part inferred from the core part and the first extremity part. The core and extremity part processors may be implemented with filters adapted to multiply each sample by a respective filter coefficient. Modifying these coefficients can introduce a frequency shift or convert the encoder for OFDM encoding.

Abstract: The invention discloses an antenna arrangement of a bonsai type, where not only the resonating frequencies may be adjusted, but also the bandwidth around some or all resonating frequencies. This is achieved by adding new branches to the trunk of the bonsai antenna arrangement. The positions and lengths of the branches are defined as a function of the frequencies around which the bandwidth should be adjusted. The antenna arrangement may be inscribed in a 3D compact volume of a specific form factor. It may also be inscribed in a planar structure. The antenna arrangement may be produced at a low cost. It may be used in a variety of applications, including communications in WiFi or other standards of multimedia content that need defined bandwidths for instance to comply to a predetermined quality of service.

Abstract: The present invention proposes a method and associated device for inserting tuples into a watermarked database without having to remove the watermarking from all or a part of the database before inserting each tuple. To achieve this, the invention consists of storing, in watermarking metadata, the type of group or class wherein the tuples of the database have been distributed during the watermarking of the database. For each type of group or class, a rule defining a modification of the value of at least one property on which the watermarking is carried is also stored in the watermarking metadata, depending on an insertion force parameter. Each tuple to be inserted is watermarked by applying the modification rule according to the group to which the tuple belongs. Due to the rule used, the insertion of the watermarked tuple does not modify the type of group it belongs to.

Abstract: The present invention proposes a rapid, reliable data extraction method for extracting data from a database of data (3) that is watermarked according to a reversible watermarking method. The method according to the invention consists of obtaining, from a first extraction request received from a client terminal (1), a second extraction request (R2) for extracting watermarked data and a third request (R3) applied to the extracted data after it has been de-watermarked. In the presence in the first extraction request of initial selection conditions relating to watermarked properties, these are included in the second request after having been transformed. In the presence in the first extraction request (R1), of aggregation functions relating to a watermarked extraction property, these are included without modification in the third request (R3) so as to supply a result to the client terminal (1) in response to the first extraction request (R1).
