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.

Effect of signal to interference ratio on adaptive beamforming techniques
Journal of King Saud University: Engineering Sciences, 2018 The capability of adaptive antenna array lies in forming higher gain in the user directions and lower gain in the interferer directions. The technique used to produce such radiation pattern by calculating the excitation weights are called the adaptive ...
