Title: Method of Forward Automatic Gaincontrol in Multi Carrier Radio Transmission
Inventor: LEE CHUNG HUI
IPC: H04B1/10
Filed: 2000-12-23
Abstract: PURPOSE: A forward AGC(Automatic Gain Control) method using a multicarrier radio transmission system is provided to simply execute correction in a system level by respectively detecting and comparing the output signals of IF surface-acoustic wave filters before three carrier waves are inputted to an IF AGC amplifier and adjusting their respective gains. CONSTITUTION: Before three carrier waves are inputted to IF AGC amplifier, a reference carrier wave among them is passed through the first IF surface-acoustic wave filter and amplified through an amplifier(S201). The amplified signal is detected by a detection part(S202). A control part tables the detected carrier wave and stores it in a memory(S203). Also the detection part respectively detects the other carrier waves through the other first IF surface-acoustic wave filters(S204). The control part also tables the detected carrier waves and stores them in the memory(S205). Then the control part compares the table value of the first carrier wave with the table value of the second carrier wave(S206). If the two values are different, the control part controls a pulse duration modulation generation part to generate a pulse duration modulation signal to an AGC amplifier, to which the second carrier wave is inputted, so that gain compensation can be made(S210). If the two values are identical, the control part makes the pulse duration modulation generation part generate a pulse duration modulation signal so as to get to the amplified level of the first carrier wave and adjusts the gain of the AGC amplifier, to which the second carrier wave is inputted(S207).
