Abstract
This paper shudies an automatic gain control(AGC) algorithm used in wireless communication cellular systems. The AGC design includes the selection of the appropriate analog-to-digital converter(ADC) and keeping the input power to the ADC constant to minimize the quantization noise generated from the analog-to-digital conversion process. In this paper the process to determine the required precision or the An is illustrated and the method to set the design parameters of the AGC is proposed. And the validity of the proposed algorithm is verified by computer simulation.
