Abstract
Automatic gain control method and apparatus control a gain of a received signal. While the gain is adjusted and thus converges, a finding mode is entered to additionally change the gain at least once according to at least one characteristic value obtained from a relationship between the gain and time, such that the gain approaches a target level. In other embodiments, a tracking mode is further entered to periodically adjust the gain at a period greater than that before when signal strength is being tracked to reduce noise energy introduced. Hence, the embodiments can improve a gain converging speed and reduce the influence of the noise on the communication system in a dynamic receiving environment, and thus enhance the signal receiving performance.
