It is well known that weight coefficients jitter in adaptive arrays does not allow to obtain a theoretical limit of the quality criterion [1, 2].

Statistical analysis of weight vector jitter in the adaptive array with gradient algorithms for the input signals with correlated samples was carried out in papers [7–10]. There it has been shown that an influence of weight coefficients fluctuations depends on value of coefficient of correlation between samples of input signals and can cause either increasing or decreasing ("overcompensation") effect of the output signal power comparing with the case when signal is processed with an optimal, constant weight vector.

In this paper there are presented computer simulation results that are aimed to checking these theoretical conclusions of the article [10].
