摘要： Provided is an auto gain control method in a digital communication system. The auto gain control method checks a distribution of a signal and a distribution of a signal envelope during a regular check interval, and determines a state of a current gain value from the distribution of the signal and the distribution of the signal envelope which are obtained through the checking of the distribution. The auto gain control method controls a gain value for auto gain control according to the determined state of the current gain value.
