Independent and Concurrent Automatic Gain Control for Wireless Communication and Spectral Intelligence
First Claim
1. A method comprising:
- allocating, from a plurality of receiver path circuits coupled to one or more receive antennas of a wireless receiver, a first set of receiver path circuits for processing a radio-frequency (RF) signal from the receive antennas into a first receive signal of a first signal class;
applying a first gain control signal to each of the allocated receiver path circuits to condition a signal level of the RF signal for the processing thereof into the first receive signal;
applying a second gain control signal to a second set of receiver path circuits to condition the signal level of the RF signal for processing thereof into a second receive signal of a second signal class distinct from the first signal class;
reallocating the receiver path circuits in response to a determination from either of the first and second receive signals that a corresponding one of the first and second signal classes is a wireless communication signal class associated with a wireless network protocol and the corresponding first and second receive signals is a wireless communication signal; and
modifying the first or second gain control signal applied to the reallocated receiver path circuits to optimize the signal level of the RF signal for processing thereof into the communication signal.

Abstract
A set of receiver path circuits is allocated for processing a radio-frequency (RF) signal provided by receive antennas coupled to the receiver path circuits. The RF signal may belong to a first signal class, such as Wi-Fi. A first gain control signal is applied to each of the allocated receiver path circuits to condition a signal level of the RF signal for the first signal class. A second gain control signal is applied to another set of receiver path circuits coupled to the receive antennas to condition the RF signal of a second signal class. First receive gain control signals are generated from the RF signals of the first signal class by the allocated set of the receiver path circuits. The first receive gain control signals are configured to optimize the signal level for processing the first signal class. A second receive gain control signal is generated to optimize the signal level of the RF signal for the second signal class.
