An AGC design of mobile cellular systems

This paper studies an automatic gain control (AGC) algorithm used in mobile cellular systems. The AGC design includes the determination of the precision of quantizer and a circuit to keep the input power of quantizer constant to minimize the quantization noise generated from the analog-to-digital conversion process. The proposed algorithm illustrates the method to determine the required precision of quantizer and to set the design parameters of the AGC in a mobile cellular system. The validity of the proposed algorithm is verified by computer simulation.
