Abstract:
A method for Automatic Gain Control (AGC) in a receiver is performed by a circuit having an inner loop and an outer loop. The method includes performing an outer loop energy detection, mitigating interference using the outer loop energy detection, and performing a frequency domain energy measurement in the inner loop. The method also includes adjusting a digital gain component in the inner loop and an analog gain component in the outer loop in response to the frequency domain energy measurement.
