摘　　要：提出一种新型数字化AGC(automatic gain control)的实现技术方案,引入PID控制算法实施对AGC智能化控制,所设计的方案已成功应用于某信号接收机。测试结果表明:该AGC实现方案具有较高的控制精度和鲁棒性,极大提高了接收机适应能力和稳定性,具有良好的应用前景。A new kind of digitized AGC（ automatic gain control） is presented. Intelligent PID algorithm is intro- duced to control AGC. The designed scheme has been applied in a signal receiver. The result indicates that the system has greater control precision, robustness, and the stability and the adaption to the environment of signal receiver has been improved greatly. The experiments show that the method is very promising.
