摘要： A coding method for a sequence of elements that can be equal to at least two distinct values, the elements forming at least one input symbol. The coding method comprises a stretching step of stretching at least one of the input symbols, to form a stretched symbol, such that the stretched symbol does not have any successive transitions. The coding method further comprises a cancelling step of canceling the disparity of the stretched symbol to form a coded symbol, such that the coded symbol comprises approximately the same number of elements of each value.

摘要： 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.

摘要： 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.

摘要： The invention concerns a method for accessing a medium by a transmit node in a synchronous communications network comprising a plurality of nodes capable of accessing said medium during access time slots of predetermined duration to transmit data frames via said network. The plurality of nodes comprises a master node that implements a clocking that defines a network cycle for accessing said medium and comprises at least two slave nodes being slaves of said clocking including said transmit node. Each network cycle comprises a plurality of frames transmitted during said access time slots according to a predetermined transmission sequence.According to the invention, the transmit mode performs the following steps: receiving at least one frame coming from at least one of the other nodes of the network; from each frame received, obtaining synchronization information pertaining to a level of synchronization of the node having sent said frame, said level of synchronization being relative to the master node; selecting a reference node from the node(s) from which at least one frame has been received, as a function of said pieces of synchronization information; determining a start of access time slot from the positions in said transmission sequence of the frames associated with the reference node and with said slave node; and accessing said medium at said determined start of access time slot.
