Abstract
A reception device includes a number of reception paths and a decoder. The reception paths are sequenced and each reception path includes a calculation module embodied to deliver a combined confidence index and a combined data stream, from the confidence index and the equalized data stream for the current path, as well as, for the subsequent reception paths after the first path, from the combined confidence index and the combined data stream, for the preceding path. The decoder is embodied to only process the combined confidence index and the combined data stream, provided by the calculation module in the last path.
Claims9
An apparatus for receiving a modulated signal, said apparatus comprising:
- a plurality of successive reception channels configured to receive a data stream corresponding to the modulated signal, each reception channel comprising:
- a module for determining a confidence index of the received data stream, and
- an equalization module configured to issue a stream of equalized data from the received data stream and from the confidence index,
- a calculation module,
- wherein the calculation module of the first reception channel is configured to issue a combined confidence index and a stream of combined data from the confidence index and from the stream of equalized data of the first reception channel, and
- wherein the calculation module of each reception channel following the first reception channel is configured to issue a combined confidence index and a stream of combined data from:
- the confidence index of the current channel,
- the stream of equalized data of the current channel,
- the combined confidence index of the preceding channel, and
- a stream of combined data of the preceding reception channel,
- a decoder configured to process the combined confidence index and the stream of combined data issued only from the calculation module of the last channel.
