Patent ID: 7555076

Claim:
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.
