  • Patent number: 9577734
    Abstract: A method of configuring a beam forming antenna in a communication network that comprises a first node where the beam forming antenna is located, second nodes and at least one destination node, communication links being established between said first node and said at least one destination node through at least some of said second nodes. The method comprises: emitting a signal by the beam forming antenna configured with a first set of antenna parameters; the same signal being sent from the first node to several second nodes; obtaining, for a plurality of communication links through which the signal has been sent, at least one physical magnitude representing the distortion caused by each communication link to the signal; aggregating said physical magnitudes of said plurality of communication links; and obtaining a second set of antenna parameters for configuring the beam forming antenna in accordance with said aggregated physical magnitudes.

  • Patent number: 9559724
    Abstract: A method and device for decoding a plurality of packets of same data. Each packet is encoded using a product code. An encoded packet comprises data blocks is organized into rows and columns. Each of the rows and columns has a respective error detecting code. For a data packet, Erroneous row and column data are detected by their associated error detecting code. In the data packet, a potentially erroneous data block belonging to a row and a column of data blocks both having been detected as erroneous is detected. In another data packet of the same data, a non-erroneous data block corresponding to the identified potentially erroneous data block is determined. The data block is determined as non-erroneous if it belongs to at least one row or column of data having been detected as non-erroneous. The identified potentially erroneous block is replaced with the determined non-erroneous block.

  • Patent number: 9420225
    Abstract: A method of transmitting a video frame over a plurality of communication channels involves selecting a number of communication channels available between the transmitting and the receiving devices; partitioning spatially correlated pixels of the video frame into a number of different partitions equal to the number of selected communication channels; and transmitting the different partitions, where each partition is transmitted on a distinct communication channel among the selected communication channels. Such a method is suitable for use in a communication system, especially a wireless communication system, in which data of a channel can be lost or corrupted. The method can maximize diversity in the transport of the video frame pixels and improve robustness.

  • Patent number: 9300979
    Abstract: A method is proposed for transmitting at least two data contents by means of a source node to a destination node via at least two transmission paths. The method for transmitting includes steps of: sub-dividing each content into a succession of elementary data groups according to a predetermined pattern of repetition comprising at least two types of different elementary groups; transmitting elementary groups on at least one of the paths, according to a predefined alternation of elementary groups resulting from the sub-division of at least two different contents.

  • Patent number: 9019873
    Abstract: Methods and apparatus for communicating between a first node and a plurality of second nodes in a network, including a first uplink mode in which a first message is transmitted from multiple second nodes in sequence, and a second uplink mode in which a second message is sent from only a subset of nodes. A first receiving node evaluates communication path information based on messages received in the first uplink mode and returns this information via an acknowledgement to allow the subset to be selected. The first message from multiple nodes includes sequence information to allow the first node to acknowledge at an appropriate point in time. This is particularly applicable where multiple spatially separated antennas offer a receiver several observations of the same signal in an antenna diversity scheme.

  • Patent number: 8494567
    Abstract: It is proposed a method for selecting an effective angle of reception of a directional antenna of a receiver node, the receiver node belonging to a wireless communications network comprising a plurality of emitter nodes. The method is implemented by the receiver node and comprises steps of: determining at least two possible angles of reception associated with a first emitter node, and for each of said at least two possible angles of reception, determining a difference between that angle and an angle of reception associated with a second emitter node different from said first emitter node, and selecting the effective angle of reception from among said at least two possible angles of reception associated with said first emitter node as a function of the determined differences.

  • Patent number: 7747783
    Abstract: The communication method concerns communication stations adapted to communicate with each other when a base station supplies a synchronisation signal to mobile stations synchronising on this signal. This method includes a request operation (901) during which a first base station (300) transmits, to a mobile station (301), a request for the storage in memory and transmission, by said mobile station, of a message, to a message destination communication station (302) which is not synchronised with said first base station.

  • Patent number: 7116645
    Abstract: The communication method of the invention applies to communication stations adapted to communicate with each other when at least one of said communication stations supplies a control signal, said station then functioning in “base station” mode and the stations not supplying a control signal then functioning in “mobile station” mode. The method of the invention includes, for at least one communication between two communication stations functioning in mobile station mode, in connection with a first base station: an operation of determining a second station, during which a communication station functioning in mobile station mode able to function in base station mode is determined, a switching request operation during which a message representing a request to switch into base station mode is sent to the second station determined during the determination operation.
