Modular device for multiple reception of a modulated signal

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 ( 1 to 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 ( 24 i) 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 ( 24 N) in the last path (N). The above particularly finds application in the reception of multi-channel signals for hertzian digital television.
