    摘要： 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.

    摘要： A device for the reception of digital data broadcast at a high bit rate for reception by mobile receivers is disclosed. The device operates under adverse conditions of multiple propagation corresponding to the Rayleigh process and imperfect frequency tuning to minimize the inter-symbol interference in the frequency domain. The device receives a digital signal having digital elements distributed in the frequency-time space f-t and transmitted in the form of symbols each constituted by a multiplex of N orthogonal carrier frequencies modulated by a set of digital elements and broadcast simultaneously. The device includes a module for transposition by a local oscillator, baseband filtering and analog-digital conversion, a temporal windowing module for the selection of the useful samples and a mathematical transformation module, the temporal windowing module applying a Nyquist window type of temporal window with non-zero roll-off.
