摘要： Disclosed is a method for controlling power level of received signal in an ultra wide band transmission system which uses multi frequency bands, and includes a pre-gain controller (PGC) and a voltage gain amplifier (VGA). The method for controlling a power level of a received signal includes the steps of: a) at the PGCs, detecting which multi frequency band is used in a transmitter of the transmission system; b) at the PGCs, obtaining the voltage gain owing to the discrepancy in the power levels of the received signals; and c) at the PGCs, compensating for the power loss based on the voltage gain.
