RECEPTEUR DE COMMUNICATION RADIO ANNULANT LA POLARISATION CROISEE D'UN SIGNAL RECU

L'invention concerne un récepteur de communication radio recevant un signal radio (S) comprenant une polarisation principale (MAIN-POL) et une polarisation secondaire (X-POL) orthogonale à la polarisation principale (MAIN-POL), le récepteur comprenant : - une unité (1) de réception du signal synchronisée sur la polarisation principale (MAIN-POL) ; - une unité (2) d'annulation de la polarisation secondaire synchronisée sur la polarisation principale (MAIN-POL) et configurée pour supprimer le signal reçu destiné à la polarisation secondaire (X-POL). The invention relates to a radio communication receiver receiving a radio signal (S) including a main polarisation (MAIN-POL) and a secondary polarisation (X-POL) orthogonal to the main polarisation (MAIN-POL), the receiver including: a unit (1) for receiving the main polarisation (MAIN-POL) and the secondary polarisation of the received signal, synchronised as a carrier frequency with the main polarisation (MAIN-POL); a unit (2) for cancelling out the secondary polarisation synchronised with the main polarisation (MAIN-POL) and configured to suppress, from the received signal (S), the interference due to the secondary polarisation (X-POL), the unit (2) for cancelling out the secondary polarisation including a filtering unit (21) that receives the main polarisation (MAIN-POL) and the secondary polarisation (X-POL) as input; a unit (3) for demodulating the filtered signal, located downstream of the cancellation unit and configured to calculate carrier frequency error information and to communicate same by feedback to the upstream receiving unit (1).
