1. A radio frequency (RF) receiver, comprising:
- a down-converter operable to convert a received RF signal to an intermediate frequency (IF) signal, the down-converter also being operable to generate a power detection signal representative of a power level associated with the received RF signal;
a hardware demodulator operable to demodulate the IF signal in accordance with a first modulation format and thereby generate a first demodulated signal; and
a digital signal processor operable to process the power detection signal in accordance with a second modulation format and thereby generate a second demodulated signal.
