Abstract
The article discusses the problems of direct spread spectrum signal’s parameters estimation and estimation performance analyzing. The achieved estimation variances compared with the corresponding Cramer ‒ Rao bounds as a rule. The proposed approach makes it possible to determine the bounds for signals of various types of modulation and spectral characteristics. The dependences of the Cramer ‒ Rao bounds on the signal-to-noise ratio, the spread spectrum sequence length and the duration of the observation interval are presented.
