Abstract:
Equalizing and decoding apparatus including in series a plurality of equalizer and weighted output decoder modules, each module except a first module receiving a stream of channel samples that has been delayed by a quantity equal to the processing time of the preceding modules, wherein each module except the first module includes a weighted output decoder and an equalizer having a first transversal filter which is a filter adapted to receive the stream of delayed channel samples and which is capable of reducing noise power, and in each module except the first module, each said equalizer includes a second transversal filter which is adapted to receive a stream of symbol mean values from the output of the preceding module and which is capable of reconstructing the intersymbol interference present at the output of the first transversal filter, the output of each said equalizer corresponding to the outputs of the first transversal filter minus the intersymbol interference as reconstructed by the second transversal filter.
