ABSTRACT:
A wireless receiver (100) is provided, comprising: a non-coherent signal detector (130) configured to receive an incoming signal and perform a non-coherent signal analysis in response to a first control signal; a coherent signal detector (140) configured to receive the incoming signal and perform a coherent signal analysis to extract coherently-encoded data from the incoming signal in response to a second control signal; and a receiver circuit (160) configured to process the coherently-encoded data. The non-coherently-encoded data provides an indication as to whether the incoming signal includes the coherently-encoded data, and the coherent signal detector is further configured to enter in a low power sleep state in response to a third control signal.
