Abstract:
In one embodiment, the present invention includes a method for receiving an incoming radio frequency (RF) signal in a receiver, estimating a signal-to-noise ratio (SNR) of a constant modulus (CM) signal in the incoming RF signal based on a calculated magnitude of the incoming RF signal, and indicating presence of a modulated signal in the incoming RF signal if the estimated SNR is greater than a threshold.
