An automatic gain control method of a receiving apparatus is provided. The automatic gain control method includes low-noise amplifying a signal using a first gain value, amplifying the low-noise amplified signal to a second gain value, determining the first gain value using a strength of the low-noise amplified signal, and determining the second gain value using the signal amplified to the second gain value. Accordingly, the reliability of the automatic gain control may be guaranteed.
