1. A method comprising: allocating, from a plurality of receiver path circuits coupled to one or more receive antennas of a wireless receiver, (i) a first set of the receiver path circuits for processing a radio-frequency (RF) signal from the receive antennas into a first receive signal of a first signal class, and (ii) a second set of the receiver path circuits for processing the RF signal into a second receive signal of a second signal class distinct from the first signal class; first processing the first receive signal according to a wireless network protocol; second processing the second receive signal exclusively of requirements of the wireless network protocol; generating a first gain control signal in accordance with training data according to the wireless network protocol contained in the RF signal, and applying the first gain control signal to the first set of the receiver path circuits to condition a signal level of the RF signal for the processing thereof into the first receive signal; generating a second gain control signal independently of generating the first gain control signal and exclusively of the training data according to the wireless network protocol, and applying the second gain control signal to the second set of the receiver path circuits to condition the signal level of the RF signal for processing thereof into the second receive signal; reallocating at least some of the second set of the receiver path circuits to the first set of the receiver path circuits in response to a determination from the first processing that the first signal class is a wireless communication signal class associated with the wireless network protocol and the first receive signal is a wireless communication signal; and modifying the first or second gain control signal applied to reallocated receiver path circuits to optimize the signal level of the RF signal for processing thereof into the first receive signal that is determined to be the wireless communication signal.
