Abstract

One of the most characteristic sources of nonlinearities in adaptive antenna arrays (AAA) is a multiplier incorporated in basic algorithms having correlation feedbacks. Let us consider their influence with regard to the two most typical algorithms for the control of AAA, which are synthesized according to the criteria of the minimum mean-square deviation of the received signal from the reference signal (MMSD) and the maximum ratio between the useful-signal power and the sum of the interference and noise power (MSNR).
