Patent ID: 10554451

Abstract:
Embodiments of the inventive concepts disclosed herein are directed to systems and methods for signal processing. An antenna array can receive signal information. A signal processing device can perform a time-domain-to-transform-domain transform with N transform domain bins, on the signal information. The signal processing device can determine N covariance matrices each corresponding to a respective one of the N transform domain bins. The signal processing device can group covariance matrices from the N covariance matrices into groups of M covariance matrices. Each group can correspond to a respective group of M adjacent bins from the N bins. The signal processing device can produce a combined spatial covariance matrix for each group of M covariance matrices, by performing a weighted combination of covariance matrices within the respective group of M covariance matrices. The signal processing device can calculate spatial weights from each of the spatial covariance matrices, for anti-jamming processing.
