Abstract: The invention relates to a reception device comprising a number of reception paths (1 to N) and a decoder (30) with weighted inputs. Each reception path (1to N) receives an input of a data stream, corresponding to a modulated signal and embodied to provide a confidence index (CSIi) and an equalized data stream (Zi) from the received data stream. Said device is characterised in that the reception paths (1 to N) comprises a calculation module (24i) embodied to deliver a combined confidence index (CCSIi) and a combined data stream (CZi), from said confidence index (CSIi) and said equalised data stream (CZi) for the preceding path. The decoder (30) with weighted inputs is embodied to only process the combined confidence index (CCSIi) and the combined data stream (CZi), provided by the calculation module (24N) in the last path (N). The above particularly finds application in the reception of multi-channel signals for hertzian digital television.
