20110317651 | METHOD AND A DEVICE FOR TRANSMISSION WITH TIME-FREQUENCY MAPPING OF SYMBOLS IN SUB-CHANNELS - A method is provided for mapping data symbols at the input of a multi-carrier modulator, which data symbols are interleaved in blocks of K symbols, into sub-channels of size equal to N | 12-29-2011 |
20120307921 | METHOD FOR SELECTING A TRANSMISSION MODE - 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. | 12-06-2012 |
20130003884 | METHOD FOR TRANSMITTING A SOURCE SIGNAL, METHOD FOR RECEIVING A TRANSMITTED SIGNAL, CORRESPONDING TRANSMITTER, RECEIVER, SIGNAL AND COMPUTER PROGRAMS - 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. | 01-03-2013 |
20130154872 | METHOD AND A DEVICE FOR LOCATING AT LEAST ONE OBSTACLE IN A COMMUNICATIONS NETWORK, A CORRESPONDING COMPUTER PROGRAM - 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. | 06-20-2013 |
