Abstract: The successive values of the digital symbols which can each take M different possible values are estimated on the basis of the successive values of digital samples each of which results from the combination of at most L successive symbols. This estimation includes a stage by stage progression through a trellis of the Viterbi type with Mk states, with k being less than or equal to Lnull1. All the states of all the stages are respectively provided with aggregate metrics. When taking into account the sample of rank n, all the transitions arriving at the various states of the current stage of the trellis are partitioned into M groups, each group containing all the transitions arising from the states of the preceding stage which are associated with one of the M possible values of the symbol of rank nnullk. The various aggregate metrics are calculated for these various states of the current stage of the trellis. One of the transitions which leads to the state provided with a extremum aggregate metric is determined in each group. A unique decision is taken regarding the value of the symbol of rank nnullk by detecting the group associated with the extremum of these M extremum aggregate metrics. This unique decision is provided with a symbol-confidence index formulated from these M extremum aggregate metrics.

Abstract: A method for estimating the impulse response of an information transmission channel includes evaluating a useful number of coefficients of an impulse response of the information transmission channel as a function of actual characteristics of the information transmission channel.

Abstract: Interpolator and decimator apparatuses and methods are improved by the addition of an elastic storage element in the signal path. In one exemplary embodiment, the elastic element comprises a FIFO which advantageously allows short term variation in sample clocks to be absorbed, and also provides a feedback mechanism for controlling a delta-sigma modulated modulo-N counter based sample clock generator. The elastic element combined with a delta-sigma modulator and counter creates a noise-shaped frequency lock loop without additional components, resulting in a much simplified interpolator and decimator.

Abstract: A method is for decoding a pulse signal modulated through a transmitted reference modulation scheme. The modulated pulse signal may include, repetitively, a reference pulse followed by an information pulse delayed with a delay. The method may include subtracting or adding from the modulated pulse signal, a version of the modulated pulse signal delayed with the delay for obtaining a processed signal, and performing a non-coherent detection on the processed signal.
