Gain compensation method and gain compensation device using a noise signal

摘要

(57) to provide a recording medium storing a program for realizing the method [Abstract] gain compensator of the path of the module in a wireless communication system, the gain compensation method is recorded. This is a device configured to be able to maintain a constant gain using the noise signals present in the signal band used, the radio frequency gain compensation system of the present invention comprises, (RF) signal the level of the noise signal of the band outside the signal band of the RF processing unit 11 to capture and to control the gain of the RF signal according to the gain control signal, and takes in the output signal from the RF processing unit, RF signal is used means 12 for detecting, and compares the level of the noise signal in the signal band which is detected by the signal level detection means and the level of the noise signal outside the signal band when the RF processing unit to maintain the reference gain, RF processing and a control unit 13 for outputting a gain control signal to the means.
