Real time implementation of separating overlapped algorithm for dual array ADS-B signal

Blog Article

In order to solve the problem of signal overlapping when communicating in ADS-B system, combined with the working characteristics of FPGA and the requirements of real-time system, chervo jacke herren the ADS-B overlapping detection algorithm and separating overlapped algorithm are optimized.Aiming at the problem that the overlapping detection algorithm needs to change the parameters to match the judgment threshold when verifying it with actual data, a method for calculating the dynamic threshold value of overlapping detection is designed, at the same time, the complex process such as eigenvector and generalized inverse matrix in the separating overlapped algorithm is optimized to invert the covariance matrix.The implementation results 2 lb m&m bag show that the optimized algorithm is suitable for real-time systems and can effectively separate ADS-B overlapped signals.
