METHOD FOR ESTIMATING A WEIGHTING VECTOR FOR AN ADAPTIVE PHASED ARRAY ANTENNA SYSTEM

摘要

The present invention discloses a low-complexity estimation method for obtaining a weighting vector for an antenna system with adaptive phased arrays. A first matrix is generated from a plurality of statistically independent symbols of the receiving signals. The plurality of statistically independent symbols is received from two or more antennas over some period of time without a prior knowledge of the properties of the symbols. A second matrix, which is the covariance matrix of the first matrix, is calculated. Subsequently, a column or row is selected from the second matrix to be the weighting vector for two or more antennas in an adaptive phased array antenna system.
