Abstract:
A method of detecting a carrier signal includes generating a first signal that represents a strength of a received signal. A variable threshold signal is generated based on the first signal. A fixed threshold signal is generated. The method includes detecting whether a carrier signal is present in the received signal based on a comparison of the first signal with a sum of the variable threshold signal and the fixed threshold signal.
