Abstract
Embodiments provide a receiver and a method for receiving data transmitted via a combination of a first signal modulated at a first carrier frequency, and a second signal modulated at a second carrier frequency, different to the first carrier frequency. In one embodiment the receiver includes a local oscillator and is configured to adaptively configure the local oscillator to operate at a first local oscillator frequency and a second local oscillator frequency, different to the first frequency, in dependence on a signal strength of the first signal relative to a signal strength of the second signal.
Claims22
A receiver for receiving data transmitted via a combination of a first signal modulated at a first carrier frequency, and a second signal modulated at a second carrier frequency, different to the first carrier frequency, the receiver comprising a local oscillator and the local oscillator being configured to adaptively operate at a first local oscillator frequency and a second local oscillator frequency, different to the first frequency, in dependence on a signal strength of the first signal relative to a signal strength of the second signal, wherein said first local oscillator frequency is substantially halfway between said first carrier frequency and said second carrier frequency.
A method of configuring a receiver to receive data transmitted via a combination of a first signal modulated at a first carrier frequency, and a second signal modulated at a second carrier frequency, different to the first carrier frequency, the method comprising:
- identifying a first signal strength corresponding to the first signal;
- identifying a second signal strength corresponding to the second signal;
- and
- configuring a local oscillator to adaptively operate at a first local oscillator frequency and a second local oscillator frequency, different to the first frequency, in dependence on the identified first signal strength relative to the identified second signal strength, wherein the first local oscillator frequency is substantially halfway between said first carrier frequency and said second carrier frequency.
