SPECTRAL CORRELATION CHARACTERISTICS OF AN ADAPTIVE ANTENNAARRAY TUNED BY THE HEBB ALGORITHM WITH ALLOWANCEFOR THE WEIGHT-VECTOR FLUCTUATIONS

摘要

In this paper, we present the results of statistical analysis of the characteristics of an adaptiveantenna array tuned by the Hebb algorithm with allowance for the weight-vector fluctuationsin the case where signals with different levels of autocorrelatedness of the input-signal readoutsarrive at the antenna array. Expressions for the correlation function of the output signal andthe power spectral density at the antenna-array output are obtained. It is shown that fluctuationslead to distortions of the output signal of the adaptive antenna array and appearance of additionalterms in the formulas for these characteristics.
