Adjust Received Signal Power by Using AGC

This model uses an AGC block to adjust the received signal power to approximately 1 watt.

A constellation diagram displays the signal before and after the signal level is adjusted by the AGC block. Random integer-valued symbols are QPSK modulated and then the signal level is scaled down by using a Gain block. The AGC block adjusts the signal to achieve a desired power level of 1 W. A constellation diagram displays the signal input to and output from the AGC block.

Run the model and display the constellation diagram to show the signal level adjustments performed by the AGC block.
