Method of the adaptive decoding of self-orthogonal codes in telecommunication

Abstract

<p>The methodology description of the adaptive multi-threshold decoding of self-orthogonal codes in the telecommunication channels of information transfer is shown in this paper. The method of multi-threshold decoder modification is described on the basis of adaptive filtration algorithms. Principles of adaptive algorithms application provide for necessary data transmission validity in the case of the multi-threshold decoding are explored. The graphic charts of multi-threshold decoders noise immunity of self-orthogonal block and convolutional codes are presented. It is determined the coding gain (CG) for multi-threshold decoding schemes. The result of research conducted in the course of the paper is to develop a set of scientifically grounded theoretical positions and practical recommendations and proposals for the development of mechanisms of formalization of description of method of increasing of noise immunity of telecommunication systems transmitting information to the synthesis and improving receiver circuit modulated signals on the theory and practice the use of signal-code constructions (SCC) when deciding maximize system capacity information transmission in the presence of noise.</p>

Analyzing the code structures of multidimensional signals for a continuous information transmission channel

“…The authors of [18], against the background of research into the method of adaptive decoding of auto-orthogonal codes, consider certain issues of estimation of the effectiveness of their use in telecommunication networks. However, the issue of analyzing the entire complex of code constructs and assessing the impact on their effectiveness exerted by the signal distance is not considered.…”

“…At dimensionality 16 of HS, example 1 with codes[4,4,1] 2 ,[4,3,2] 4 ,[4,1,4] 3 produces 218 •12 signals. The structure of example 3 with the same dimensionality and distance gives (2 4 -1)•2 8 =2 8 •15 signals.…”
