Abstract: In this letter, we propose a new approach to justify a roundoff error’s impact on the accuracy of the linear multi-antenna receiver based on Cholesky decomposition. This decomposition is used in the minimum mean square… read more here.

DOI: 10.1109/taes.2025.3566361
Abstract: The performance of the conventional sample matrix inversion beamformer significantly degrades due to mismatches between the actual and presumed statistical models of the array data. Recently developed robust adaptive beamformers (RABs) combat the aforementioned mismatches… read more here.
