Diagonal Loading Beamforming Based on Aquila Optimizer
IEEE Access, 2023 Traditional beamforming algorithms are only applicable to ideal environments. When the array antenna receives data under circumstances of small snapshots or large signal-to-noise ratio(SNR), noise eigenvalues of classic sample matrix inversion(SMI) and ...

On robust capon beamforming and diagonal loading
IEEE Transactions on Signal Processing, 2003 The Capon (1969) beamformer has better resolution and much better interference rejection capability than the standard (data-independent) beamformer, provided that the array steering vector corresponding to the signal of interest (SOI) is accurately known.

Broadband Beamforming Using the Least Square Method Improved via Adaptive Diagonal Loading [PDF]
Journal of Electromagnetic Engineering and Science, 2023 The least square method (LSM) is a commonly used beamforming method. However, it limits the beamforming frequency bandwidth and is vulnerable to noise; therefore, diagonal loading is used to overcome these limitations.

A CLT on the SNR of Diagonally Loaded MVDR Filters [PDF]
IEEE Transactions on Signal Processing, 2012 This paper studies the fluctuations of the signal-to-noise ratio (SNR) of minimum variance distorsionless response (MVDR) filters implementing diagonal loading in the estimation of the covariance matrix. Previous results in the signal processing literature are generalized and extended by considering both spatially as well as temporarily correlated ...
