Development of a method for calculating the noise immunity of a synthesized algorithm for specific information systems

DOI №______

Abstract

In the article the method of calculation of noise immunity of the synthesized algorithm for the concrete systems at use of multiposition signals is considered. The proposed algorithm for coherent processing of multiposition AFMs or signals is particularly suitable for multi-channel (multifrequency) systems with orthogonal channel signals, because in these systems, the same procedures for calculating the projections of the received signal into two mutually orthogonal reference oscillations with an arbitrary initial phase are used in these systems for the orthogonal signal section.
Perspective of the active formation of digital networks as an alternative to existing analogue communication channels, in order to ensure the technical and technological development of telecommunications. This article is devoted to the research and development of methods for optimal reception of multiposition signals by demodulators of multichannel modems, which contribute to improving the quality of information transmission in digital form by communication channels of various types.

Keywords: noise immunity systems; multiposition signals; discrete signaling ensembles; two-dimensional signaling ensembles; signal/noise ratio; noise immunity coefficient; probabilistic signals; error probability.
