Abstract
The invention relates to a telemetry system for a motor vehicle comprising a reception module (3) comprising a plurality of elementary acquisition modules (32) each capable of generating an elementary detection signal (Sde); and a calculation unit (4) capable of detecting in each elementary detection signal (Sde) received, the presence of a predetermined data sequence (Seq); characterized in that in the absence of detection of said data sequence (Seq) in a first elementary detection signal (Sde1) generated by a first elementary acquisition module (321), the calculation unit (4) is arranged to generate a combination of said first elementary detection signal (Sde1) and a second elementary detection signal (Sde2) generated by a second elementary acquisition module (322) adjacent to the first elementary acquisition module (321) and to detect the presence of said data sequence (Seq) in said combination.Figure to be published with the abstract: Fig. 1.
