Abstract :
We develop a novel, microwave beamforming algorithm based on the minimum mean-square error (MMSE) criterion. Relative to perturbation algorithms, the proposed method requires only a fraction of weight changes to estimate the beamformer weights, thereby making it more suitable for high-data-rate applications. Numerical simulations reveal that the proposed algorithm offers promising performance and is less susceptible to performance degradation than the perturbation algorithm when used with slow-switching and/or finite-resolution phase shifters and amplitude-control devices.
