Abstract
A method is provided for receiving a multicarrier signal in a receiver implementing at least two distinct reception channels. After receiving the multicarrier signal during a first step, and in order to optimize subsequent processing (such as synchronization, confidence computing, . . . ), information representing the reception quality is associated to each corresponding reception channel during a second step. An embodiment of the disclosure relies on a new way of computing this information, called absolute confidence, which takes account on the one hand of the reception quality of the considered channel compared to the other channels (total confidence) and on the other hand of the reception quality of each source data (carrier) compared to the others, in the considered channel (relative confidence), to determine an absolute confidence for each data of each channel.
