Angular Beamforming Technique for MIMO Beamforming System
International Journal of Antennas and Propagation, 2012 The method of MIMO beamforming has gained a lot of attention. The eigen beamforming (EB) technique provides the best performance but requiring full channel information. However, it is impossible to fully acquire the channel in a real fading environment.

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.
