Abstract
A measurement signal, the measurement signal indicative of a bias in a signal received via a communication channel, is generated. A detection signal, the detection signal indicative of presence of an unmodulated radio frequency (RF) carrier prior to a communication frame in the signal received via the communication channel, is generated using the measurement signal.
