Linear Scrambler Identification

Abstract

The article describes algorithm that allows determining scrambler type based on the signal from its output. The task of this kind is relevant for radio monitoring systems and when creating cognitive systems for digital signal receiving and processing. The identification algorithm determines the form of the scrambler both multiplicative and additive. There are no published papers providing algorithm for automatic determination of scrambler type. This article is intended to partly fill the gap. It provides a form al statement of the problem, an identification algorithm and simulation results.
