摘要： Estimation of symbols related to each other by a parity relationship previously created by an encoder, is effected by a function having several components effecting a calculation of probabilities corresponding to a state of the encoder. The probabilities are of a first type, resulting from the observation of the effects of the previous states of the encoder on the current state, of a second type, resulting from the observation of the effects of the subsequent states of the encoder on the current state, and of a third type, representing the belonging of a symbol to a predetermined part of an encoding alphabet. A specific multiplexer is controlled by a state machine and cooperates with a calculator so that not only the probabilities of the first and second types but also the probabilities of the third type are obtained by one and the same circuit.

摘要： A transmitting apparatus transmits a plurality of data packets to a receiver in a communication system, by transmitting one or more data packets from a list of data packets to be transmitted, and determining whether an acknowledgment is received for each transmitted data packet. When it is determined that an acknowledgement has not been received for at least one data packet, referred to as an unacknowledged data packet, the apparatus selects one or more additional data packets from the list of data packets to be transmitted, generates one or more parity packets by encoding a block of data containing a combination of the selected one or more additional data packets and at least one unacknowledged data packet using a forward error correction scheme, and transmits at least one of the generated parity packets.

摘要： A method of decoding a one-point algebraic geometric code defined on an algebraic curve of the kind C(a,b), represented by an equation of degree b in X and of degree a in Y. For any received word, transmission errors affecting the received word are located. The correction of errors in the word, which belongs to an algebraic geometric code, is then reduced to the correction of errors in a certain number, at most equal to a, of words belonging to a Reed-Solomon code. Devices and apparatuses adapted to implement this method are also described.

摘要： In order to evaluate the noise related to data issuing from a turbo-encoder, estimates of the noise related to its systematic output, to the data issuing from its first elementary encoder, and to the data issuing from its second elementary encoder are determined. At least two of the estimates of the noise related to the systematic output, to the data issuing from the first encoder, and to the data issuing from the second encoder, are added. The results of these additions are divided by the number of augends added, and then inverted, so as to obtain a noise factor, and the noise factor is multiplied with the data issuing from at least one of the first encoder, second encoder, and systematic output.

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： 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 Fq, comprising the following steps: —calculating extended error syndromes (σj(i)) associated with a received word (r); —determining the values of errors in each component (r(x, yp(x))) of the received word r, on the basis of the extended error syndromes calculated. Since the error value is determined for each component, it is not necessary to have recourse to an error locating step. The invention also relates to devices and apparatuses associated with the method.
