Abstract: A method and apparatus are provided for locating an obstacle between a transmitter and a receiver. The method includes: determining at least one elliptical ring in which the obstacle is situated, the elliptical ring being defined by two confocal ellipses, having their focuses corresponding to the transmitter and to the receiver, each elliptical ring being associated with a physical echo generated by an obstacle; estimating a distance between the obstacle and a focus as a function of the separation between the confocal ellipses at the obstacle in a plane normal to the axis defined by the focuses so as to obtain a set of potential location zones for the obstacle in the elliptical ring; and lifting the ambiguity between the various potential location zones of the obstacle so as to deliver a location zone of the obstacle.

Abstract: The invention concerns a method for demodulating a digital signal received via a transmission channel, comprising a step which consists in associating with each value received of said received signal a point of the corresponding modulation constellation, on the basis of the decision boundaries taking into account the potential effect of a phase shift on at least one of said points of the modulation constellation and of the potential effect of an Gaussian additive noise applied on said point, said Gaussian additive noise being represented by a generating surface associated with said point, and said phase shift by a rotation on an angular range based so that said swept surface belongs essentially to the region of decision associated with the corresponding point of the modulation constellation, plotted on the basis of at least one phase and/or amplitude characteristic of said modulation, so as to associate with each of said points of the constellation a portion of a reception space, called corresponding region of decision.

Abstract: A method and device are provided for selecting a transmission mode, for a first telecommunications entity having a plurality of different modes for transmitting a communications signal to a second telecommunications entity. The various transmission modes provide the same data rate D. The method includes: for a given transmission mode, determining the value of a first metric α that measures degradation relating to a given distance d stemming from the transmission medium of the communications signal for a given environment compared with a reference model for the transmission medium, as a result of a multi-path effect and/or of an attenuation effect of the transmission medium; and comparing values of the metric α for different modes in order to select at least one transmission mode.

Abstract: A method and apparatus are provided for transmitting a source signal including a plurality of binary sequences to NR receiving antennas, where NR is no lower than 2. The method implements, for at least one first binary sequence of the source signal, pre-filtering for focusing a signal to be transmitted on at least one of the reception antennas, referred to as the target antenna. The target antenna and the associated focus pre-filtering step are selected according to a value of the first binary sequence intended for being considered as received. The method also includes transmitting the pre-filtered signal.

Abstract: A method and a device (4) for block interleaving of size K with N iterations of index j, N being greater than or equal to 1, of input digital data items indexed by a variable k={0, . . . , K−1}. The interleaving method uses a turbo structure that has two inputs and one output. At the end of each iteration j, the interleaving law I(j)(k) at the output of the interleaver (4) is modified in accordance with an input sequence formed by the position indices of the data items before interleaving (typically a ramp) and in accordance with an interleaved sequence (which provides the position of the data items after interleaving) resulting from the previous iteration of the same interleaving algorithm.
