Abstract
A new calculation technique of accuracy characteristics of multichannel measurer was offered, ensuring essentially more exact results in comparison with the known ones. The expressions for the signal parameter maximum likelihood estimate bias and variance were found, in case of the multichannel reception of the quasidetermined or random signal and while the prior distribution of the informative parameter and the number of channels can be any. The influence of the value of the prior interval length and the number of channels on the accuracy of this estimate was investigated. The procedures were specified of the minimal channel number choice with the predetermined error of measurement. By statistical modeling methods the range of applicability of the theoretical formulae was established for the estimate characteristics, with the different numbers of channels and signal-to-noise ratios.
