1. A MIMO-based system comprising an Automatic Gain Control (AGC), wherein the AGC is calibrated by way of an iterative process, the iterative process comprising:
- transmitting a calibration signal;
receiving the calibration signal;
decoding the calibration signal to produce measurements;
storing the measurements;
changing an AGC gain setting; and
increasing transmission power by L decibels after an AGC gain setting is decreased by L decibels, wherein L is specified by an end-user.
