METHOD AND APPARATUS FOR CONTROLLING GAIN IN COMMUNICATON SYSTEM SUPPROTING BEAM FORMING SCHEME

摘要

A signal reception apparatus in a communication system supporting a beam forming scheme is provided. The signal reception apparatus includes a Low Noise Amplifier (LNA) configured to generate a second signal by amplifying a first signal according to a first gain value, a Variable Gain Amplifier (VGA) configured to generate a third signal by amplifying the second signal according to a second gain value, and an Automatic Gain Controller (AGC) configured to control the first gain value and the second gain value by considering a plurality of beam types supported in a signal transmission apparatus.
