Abstract: Most of beamforming methods rely on the proper estimation of the steering vectors of the incoming signals in order to calculate appropriate array feeding weights. However, this estimation is ...

Abstract: In this letter, a machine learning-based algorithm, K-nearest neighbor, is employed to predict the actual patterns of the linear arrays with arbitrary positions and varied element numbers.

Dynamic arrays have brought significant flexibility to Excel, allowing formulas to automatically expand or contract across cells. However, this functionality introduces a common issue: formatting ...
