Abstract

One of the directions to improve the efficiency of modern telecommunication systems is the transition to the use of multidimensional signals for continuous channels of information transmission. As a result of studies carried out in recent years, it has been established that it is possible to ensure high quality of information transmission in continuous channels by combining demodulation and decoding operations into a single procedure that involves the construction of a code construct for a multidimensional signal. This paper considers issues related to estimating the possibility to improve the efficiency of continuous information transmission channel by changing the signal distance of the code structure. It has been established that the code structures of such types as a hierarchical code construct of signals, a hierarchical code construct of signals with Euclidean metric, a reversible code construct of signals, a reversible code construct of signals with Euclidean metric have the potential, when used, to increase the speed of information transmission along a continuous channel. With a signal distance reduced by 10 percent or larger, it could increase by two times or faster. The estimation of the effect of reducing a signal distance on the efficiency of certain types of code structures was carried out. It has been established that the hierarchical reversible code construct, compared to the hierarchical code construct, provides a win of up to two or more times in the speed of information transmission with a halved signal distance. Implementing the modulation procedure has no fundamental difficulties, on the condition that for each code of the code construct the encoding procedure is known when using binary codes. The results reported here make it possible to build an acceptably complex demodulation procedure according to the specified types of code structures

Summary

Introduction

One of the directions to improve the efficiency of modern telecommunication systems is the improvement of existing and the construction of new methods of modulation and interference-resistant coding for continuous signal transmission channels. Increasing the requirements for the speed and volume of information transmission required the search for new promising theoretical principles for increasing the efficiency of modulation and decoding in continuous signal reception channels One of these areas is research aimed at assessing the effectiveness of the use of code structures of multidimensional signals in combination with interference-resistant codes. The question of assessing the possibility of the influence of parameters of code structures of multidimensional signals on the effectiveness of the use of a continuous channel of information transmission is a relevant scientific task. Will make it possible to assess the impact of changes in a signal distance on the effectiveness of a continuous information transmission channel
