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 |

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 |

20140157093 | METHOD AND DEVICE FOR IMPROVING DECODING OF DATA RECEIVED FROM ONE SOURCE BY SEVERAL RECEIVERS - Improving decoding of a set of k data symbols received from several receivers, the data symbols being encoded by a systematic block error correcting code of dimension k and size n. The set of data symbols is received along with a corresponding subset of parity symbols, forming a partial data block comprising m symbols. A partial data block transmitted by one emitter, comprising a set of k data symbols and a subset of (m−k) parity symbols, is received from each receiver. For each received partial data block, a subset of parity symbols is generated and an item of reliability information is computed as a function of the received parity symbols and parity symbols generated from a received set of data symbols. The items of computed reliability information are compared with each other to select one received set of data bits. | 06-05-2014 |
