SETTING UP METHOD AND APPARATUS FOR AGC ADAPTIVE LOOP BANDWIDTH AT THE VARIABLE WIRELESS CHANNEL ENVIRONMENT

摘要

The invention actively respond to the automatic gain control loop adaptive bandwidth in accordance with the change of the wireless channel A method and apparatus, the method calculates the difference between the desired power level the received signal and the process to obtain the average value of power for a predetermined period to change to a digital signal, on the average value of the power, and outputting a power error process and, by using a gain coefficient table in advance to have screen memory resistor to the power error is input every second, the each and outputting by setting the appropriate gain constant According to another register value, wherein the output gain constant and outputting the error and the power multiplied by the power gain value, the accumulated value of the output power gain for a period of time after, the update rate and outputting the accumulated gain of the predetermined length for each cycle, the output of a predetermined length using the gain value characterized in that it comprises the step of adjusting the gain of the received signal.
