Assessment of digital channels of communication with defined reliability characteristics

Abstract

In the classical theory of telecommunications, an indicator of reliability is the probability of an information bit error. In modern international standards and recommendations, there is a hierarchy of quality indicators of the communication channel based on measurements, which is not related to the classical theory of noise immunity. The procedures for measuring the quality indicators of information transmission are possible only when using an already existing telecommunication system. The use of the classical theory of noise immunity makes it possible to provide for the correspondence of the energy parameters to the necessary quality indicators for the future communication system. The research aims to develop a unified methodology to assess the quality of communication channels and combine the classical theory of telecommunications with international recommendations and standards. To find the relationship between them, we analyzed existing methods of assessing the quality of communications channels, developed an algorithm for assessing the quality parameters and analyzed the characteristics of the channel. The methodology helps to assess the level of compliance of the quality parameters of information transmission through the channels of existing digital telecommunication systems with the requirements of international standards and recommendations. It is possible to research the behavior of quality indicators and optimize the operation of existing and design new digital communication channels according to the criteria of the quality of information transmission in accordance with the requirements of international standards and recommendations.
