MOBILE COMMUNICATION RELAY SYSTEM AND METHOD THEREOF

摘要

PURPOSE: A mobile communication relay system and a method thereof are provided to control the gain according to monitoring of a input signal about each relay device and control the on/off of ALC(Automatic Level Control) or AGC(Automatic Gain Control), thereby steadily operating mobile communication relay. CONSTITUTION: A level measuring unit(12) measure the level of input signal. A comparison unit(14) compares the level of the measured signal with the preset reference level. If the level of measured signal is higher than the preset reference level, a control unit(16) maintains regular output by operation of the ALC(Automatic Level Control) or the AGC(Automatic Gain Control). If the level of measured signal is lower than the preset reference level, the controller offs the operation of the ALC or the AGC.
