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.

본 논문은 무선통신 시스템에서 사용되는 자동이득조절(AGC) 알고리즘에 관한 것이다. AGC 설계는 적합한 analog-to-digital converter(ADC)의 선정과 analog-to-digital 변환 과정에서 발생되는 양자화 잡음을 최소로 하기 위해 ADC로 입력되는 신호 전력을 일정하게 유지시키는 것을 포함한다. 본 논문은 요구되는 ADC의 정밀도를 결정하는 과정을 설명하고 AGC 설계 parameter들을 결정하는 방법을 제시한다. 또한 모의실험을 통해 제시한 알고리즘의 타당성을 검증한다.
