Patent ID: 8594559

Claim:
A satellite digital radio receiver for receiving first and second radio services, broadcast in first and second respective different radio frequency bands, wherein at least one radio programme is broadcast substantially simultaneously on both radio services, and wherein one of the frequency bands can produce interference in the other frequency band, the receiver comprising: a shared mixer circuit, configured to receive and down-convert signals in a bandwidth comprising both of the frequency bands to signals of lower frequency; a first processing circuit, coupled to the output of the mixer circuit and configured to demodulate the first radio service; a second processing circuit, coupled to the output of the mixer circuit and configured to demodulate the second radio service; and a control circuit, connected to the first and second processing circuit and adapted to selectively couple the output of either the first or the second processing circuit to an output of the receiver, wherein when interference in the first frequency band, caused by the second radio service, interferes with demodulation of the first radio service by the first processing circuit, the control circuit couples the output of the second processing circuit to the output, whereby the at least one radio programme can be received from the second radio service.
