Abstract: A multiband antenna arrangement includes at least two main conductive elements, the first main conducting element resonating at a first fundamental mode of a first electromagnetic radiation and the second main conducting element resonating at a second fundamental mode of a second electromagnetic radiation, wherein the second main conductive element is connected to the first main conductive element at a feed connection located at a position defined as a function of bellies of current of the first electromagnetic radiation and the antenna arrangement has more resonating modes than the first main conductive element. The antenna arrangement may also be configured so that some of the resonating modes of the first main conductive element have a bandwidth that is enlarged in comparison to the corresponding bandwidth of these resonating modes for the first main conductive element. A design method of the antenna arrangement to provide a match between the resonating modes of the antenna arrangement and a specification defined by a list of frequencies and, possibly, corresponding bandwidths at a predefined matching level and selectivity, as well, as in certain embodiments, a predefined form factor.

Abstract: A method for locating at least one receiver in a positioning system. The system includes: at least two generators, each generator emitting, on a single carrier, at least two signals that each have a different code, and a receiver configured to detect the signals emitted by the generators. In the method: the receiver measures, for each generator, the phase difference between both signals emitted by the generator, and at least one geometric size, representing the position of the receiver in relation to the generators, is calculated on the basis of the measurements of the phase difference in order to locate the receiver in the positioning system.

Abstract: A method, device, and a computer program are provided to decode a signal received through a transmission channel in a communication system, the received signal being represented by a signal vector. The method comprises: calculating an initial estimate of a transmitted symbol vector carried by the received signal vector; calculating a bound parameter (201) from a linear function of the initial estimate of the transmitted symbol vector, the linear function being defined by a slope coefficient and an intercept coefficient, the method further comprising: determining estimated symbols representative of the transmitted symbols carried by the received signal, the estimated symbols being determined from a set of candidate lattice points, each lattice point comprising a set of components, each component of a candidate lattice point being searched in a search interval (203), the search interval having at least one search interval bound computed from the bound parameter; determining (205) the estimated symbols from the closest lattice point to the received signal vector among the candidate lattice points.

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 invention relates to data processing for sound playing on a sound playing device (DIS), headset or ear bud type, portable by a user in an environment (ENV). The device comprises at least one speaker (HP), at least one microphone (MIC), and a connection to a processing circuit comprising: An input interface (IN) for receiving signals coming at least from the microphone; A processing unit (PROC, MEM) for reading at least one audio content to play on the speaker; and An output interface (OUT) for delivering at least the audio signals to be played by the speaker. The processing unit is arranged for: a) Analyzing the signals coming from the microphone for identifying sounds coming from the environment and corresponding to predetermined classes of target sounds; b) Selecting at least one identified sound, according to a user preference criterion; and c) Building said audio signals to be played by the speaker, by a selected mixing of the audio content and the selected sound.

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: Systems and associated methods of performing coherent optical communication of quantum information between an emitter A and a distant receiver B are provided, using a local local oscillator. Examples of LLO-based Continuous-Variable Quantum Key Distribution are described. Self-coherent schemes are used, the schemes consisting in deriving both signal and phase reference pulses from the same optical pulse thus ensuring an intrinsic strong signal to reference phase coherence. Different CV-QKD designs implementing various self-coherence phase sharing schemes are described and compared in terms of secret key rate and hardware requirements. Strong phase noise resilience can be obtained with standard telecom equipment such as low cost lasers.

Abstract: An exemplary decoder is provided for decoding a signal received through a transmission channel in a communication system. The exemplary decoder comprises a transformation unit configured to determine a set of auxiliary channel matrices, each auxiliary channel matrix being determined by performing a linear combination of at least one of the column vectors of the channel matrix; a decomposition unit configured to determine a decomposition of each auxiliary channel matrix into an upper triangular matrix and an orthogonal matrix; a matrix selection unit configured to select at least one auxiliary channel matrix among the set of auxiliary channel matrices depending on a selection criterion related to the components of the upper triangular matrices. The decoder determines at least one estimate of vector of information symbols from an auxiliary signal and from the upper triangular matrix corresponding to a selected auxiliary channel matrix by applying a decoding algorithm.
