Abstract:
1. A method for accomplishing automatic gain control (AGC) for a wireless communication system comprising a plurality of amplifiers, comprising: receiving, from a baseband signal processor, an input that indicates a total amount of gain adjustment; obtaining, from a database, amplification characteristics associated with at least one of the amplifiers, wherein the obtained amplification characteristics include one or more of: a gain value, a noise figure, a nonlinearity measure, and a power efficiency measure; determining a desired performance requirement; calculating a per-amplifier-stage gain profile based on the amplification characteristics obtained from the database, the total amount of gain adjustment, and the desired performance requirement; and outputting a plurality of control signals based on the generated per-amplifier-stage gain profile, wherein a respective control signal independently controls gain of a corresponding amplifier, thereby enabling the wireless communication system to achieve the total amount of gain adjustment while meeting the desired performance requirement.
