| Abstract: | A general method is proposed after analyzing the requisite matters and related factors in designing the Wideband digital receiver AGC.It solves the conflicts between instantaneous dynamic range reduction and block interference occurring and ensures normal implementation of Wideband digital receiver in a complicated and crowded electro-magnetic environment.The composition and characteristics and performance of various AGC modules are introduced from practical engineering viewpoint.Theoretical analysis and engineering practices show effectiveness and practicability of the scheme. |
