Abstract
An equalizer-combiner for a diversity receiver using at least two receive channels computes equalization coefficients for each channel allowing for a first channel error signal representative of a comparison between the demodulated signal and a channel estimate of the transmitted source signal delivered by a channel estimator fed with the demodulated signal in the channel during an acquisition phase and a second channel error signal representative of a comparison between the demodulated signal and the global estimate of the transmitted source signal during a normal operation phase. The equalizer-combiner computes the weighting coefficients allowing for a first global error signal representative of a comparison between the combined signal and the global estimate of the source signal during the acquisition phase a second global error signal representative of a comparison between local reference information known to the receiver and corresponding received reference information periodically extracted from the global estimate during the normal operation phase.
