Abstract

Adaptive antenna arrays, also known as smart antennae, are becoming progressively a viable alternative to larger antenna structures in a wide number of different scenarios. However, in order to take full advantage of the arrays' interference rejection and SNR (Signal-to-Noise Ratio) improvement capabilities, that is, in order to perform a correct signal beamforming via complex weights' manipulation, the antenna structure needs a precise calibration procedure. In this paper, two algorithms, based on efficient MLE (Maximum Likelihood Estimation) and MEE (Maximum Entropy Estimation) are analyzed and simulated, in order to obtain their relative performance.
