20080270873 | Decoding Method for Algebraic Geometric Codes and Associated Device - The present invention relates to a method of decoding a one-point algebraic geometric code defined on an algebraic curve of type C(a,b) represented by an equation F(X,Y)=0 of degree b in X and of degree a in Y over F | 10-30-2008 |

20090037789 | METHOD OF DECODING CONTENT DATA BLOCKS, CORRESPONDING COMPUTER PROGRAM PRODUCT AND DECODING DEVICE - It is proposed a method of decoding a set of symbols to be decoded, several data blocks representative of the set of symbols to be decoded being received by a decoding node of a communications network. The data blocks are encoded by means of an error correction code enabling a decoding by erasure. The decoding node performs the following steps: a first selecting step of selecting at least one of the data blocks, a first determining step of determining first erasures, a checking step of checking whether the number of the first erasures is below a given threshold. In the event of positive determining, the decoding node performs a first decoding step of decoding by erasure of the set of symbols to be decoded. If not it performs a second selecting step of selecting at least one of the data blocks, a second determining step of determining second erasures, and a second decoding step of decoding by erasure of the set of symbols to be decoded from the second erasures. | 02-05-2009 |

20110296280 | METHOD, DEVICE AND COMPUTER-READABLE STORAGE MEDIUM FOR CONFIGURING AN OVERALL ENCODING/DECODING SCHEME IN A COMMUNICATIONS NETWORK - A method is provided for configuring an overall encoding scheme comprising a first encoding for generating first encoded packets from source packets and a second encoding for generating second encoded packets by combination of first encoded packets according to a combination scheme applied by predetermined nodes of the network. The method obtains a number N of defective paths among paths used to transmit the first and second encoded packets to at least one destination node, a path being defective if an associated quality of transmission is below a predetermined threshold. A combination scheme is selected from among at least two possible predetermined combination schemes for which a number of encoded second packets is greater than or equal to N. | 12-01-2011 |

20120260143 | METHOD OF DECODING CONTENT DATA BLOCKS, CORRESPONDING COMPUTER PROGRAM PRODUCT AND DECODING DEVICE - When decoding a set of symbols to be decoded, several data blocks representative of the set of symbols to be decoded are received by a decoding node of a communications network. The data blocks are encoded using an error correction code enabling a decoding by erasure. The decoding node performs the following steps: first selecting at least one of the data blocks, first determining first erasures, and checking whether the number of the first erasures is below a given threshold. In a case the check is positive, the decoding node performs first decoding by erasure of the set of symbols to be decoded. In a case the check is negative, the decoding node performs second selecting of at least one of the data blocks, second determining second erasures, and second decoding by erasure of the set of symbols to be decoded from the second erasures. | 10-11-2012 |

20120274513 | Method and a System for Configuring a Beam Forming Antenna in a Communication Network - 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. | 11-01-2012 |

A method of transmitting K data blocks of a data unit comprises the steps of encoding the data unit into an encoded data unit comprising N encoded blocks, with N>K, using an error correction code having a minimum distance d; and transmitting the N blocks of the encoded data unit over a set of N | 02-21-2013 |

20130082889 | CONCENTRIC MILLIMETER-WAVES BEAM FORMING ANTENNA SYSTEM IMPLEMENTATION - An antenna implementation comprises an electromagnetic lens and at least one electromagnetically shielding member. The electromagnetic lens is adapted to guide at least one electromagnetic signal by means of at least a variation in permittivity. The at least one electromagnetically shielding member encapsulates the electromagnetic lens partially so as to direct at least one electromagnetic signal propagating through the electromagnetic lens. The at least one electromagnetically shielding member can advantageously be part of an enclosure; said enclosure encapsulates partially the electromagnetic lens. The antenna can further comprise antenna transmission means that contain wave guides. Said waveguides can advantageously be incorporated into the enclosure. The antenna is particularly suited for implementations using Substrate Integrated Waveguide techniques. SIW techniques allow miniaturization of the antenna and offer the advantage of low energy consumption as may be required in portable devices. | 04-04-2013 |
