Design of High Dynamic AGC Control Model and Signal Processing Algorithm For Software Radio Receivers

Aiming at the requirements of software radio receiver AGC design and related problems, using the idea of approximate linearization control, an approximate linearization AGC control model is established, and the corresponding AGC signal processing algorithm is designed. And according to the LMS6002D radio frequency front-end circuit, the relevant working parameters are determined. Based on the software radio platform, the design and verification of the AGC hardware structure, AGC signal processing algorithm and control model are completed. Experiments show that the software radio receiver realizes the function that is high dynamic and fast AGC adjustment. This method has the characteristics of clear hierarchy, simpler implementation, less hardware resources, wide dynamic range and fast adjustment convergence.
