Abstract:
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 ).

Claim (Index 1):
A radio communications receiver receiving a radio signal comprising a main polarisation and a secondary polarisation orthogonal to the main polarisation, the receiver comprising:\n a receiving unit for receiving the main polarisation and for receiving the secondary polarisation of the received signal, synchronized as carrier frequency on the main polarisation; a cancellation unit for canceling the secondary polarisation synchronized on the main polarisation and configured to cancel, from the received signal, interference due to the secondary polarisation, the cancellation unit comprising a filtering unit receiving at input the main polarisation and the secondary polarisation to:\n filter the components in phase of the secondary polarisation contributing to interference of the main polarisation, for its components in phase and in quadrature; \n filter the components in quadrature of the secondary polarisation contributing to interference of the main polarisation, for its components in phase and quadrature; and \n add the components filtered in this way to the components in phase and in quadrature of the main polarisation such that the filtered signal coming from the filtering unit deletes the contribution of the secondary polarisation on the main polarisation, the filtered signal coming from the filtering unit comprising only the contribution of the main polarisation; and \n a demodulation unit for demodulation of the filtered signal, located downstream of the cancellation unit and configured to calculate carrier frequency error information and communicate it by retroaction to the upstream receiving unit.
