METHOD FOR CONTROLLING AUTOMATIC GAIN OF MOBILE PHONE, ESPECIALLY REGARDING TO REDUCING POWER CONSUMPTION AND TIME REQUIRED FOR STABILIZING GAIN VALUE IN AUTOMATICALLY CONTROLLING GAIN OF DISCONTINUOUS RECEIVING SIGNALS

摘要

PURPOSE: A method for controlling an automatic gain of a mobile phone is provided to reduce power consumption and time required for stabilizing a gain value in automatically controlling a gain of discontinuous receiving signals by using an AGC gain previously stored. CONSTITUTION: If a system is turned on, it is confirmed whether an effective receiving signal is inputted(S1). If so, an AGC(Automatic Gain Controller) is driven at a predetermined offset gain value(S2). When the effective receiving signal is interrupted, the current AGC output gain value is stored and the AGC is stopped(S3-S5). It is confirmed whether the effective receiving signal is inputted(S6). If so, the AGC is driven again at the stored AGC output gain(S7). It is confirmed whether the AGC driving stoppage is requested(S8).
