AI Technical Summary
Existing radio frequency signal processing technologies suffer from insufficient simulation accuracy, slow response, and lack of flexibility in electronic warfare and equipment testing, making it difficult to meet the needs of instantaneous acquisition and dynamic reconstruction. In particular, the inaccuracy and lack of adaptability in simulation are caused by the non-ideal nature of the channels themselves and the fixed parameters of the hardware.
A predistortion-based reconstruction method is adopted, which obtains channel calibration coefficients and predistortion loading coefficients through self-calibration, performs convolutional fusion to generate predistortion reconstruction coefficients, realizes the matching of channel characteristics of the device to be simulated, and uses pure digital signal processing technology for real-time calibration and configurable predistortion loading.
It achieves high-precision and fast channel characteristic simulation, solving the problems of insufficient simulation accuracy and slow response in traditional methods. It is flexible and adaptable, and can complete target switching and coefficient updates in milliseconds.
