В статье рассматриваются каскадные кодовые конструкции на основе схем произведений линейных блоковых кодов (турбопродуктивные коды, Turbo Product Codes). Исследуются методы декодирования с мягкой схемой принятия решений и процедуры обмена мягкими решениями в алгоритмах турбо декодирования. Предлагается усовершенствованный метод мягкого декодирования каскадных кодовых конструкций с итеративным обменом мягких решений. Результаты исследований могут быть использованы при разработке телекоммуникационных систем и технологий, а также при изучении учебных дисциплин по теории передачи данных, теории информации и помехоустойчивому кодированию.
This article deals with the increase of interference immunity of the discrete messages passing in the telecommunications systems and networks of the special setting, as well as in the control and connection systems on transport. To achieve this purpose the actual scientific and technical task was put. The task essence is to develop new methods of construction and decoding of cascade codes constructions with the improved properties. Mathematical apparatus of interference immunity estimation of discrete messages passing on the imitation design basic has got further development. This article discusses the structure of concatenated codes based on the schemes of linear block codes multiplication (Turbo Product Codes). The methods of decoding with soft decision logic and procedures for exchange of soft decision turbo decoding algorithms. It provides an improved method of decoding the soft cascade of code structures with an iterative exchange of soft decisions. The research results can be used for the design of telecommunication systems and technologies and in the studying of such academic disciplines as communication theory and. The empiric dependences between the correlation of signal to «signal/noise» and the probability of discrete messages error reception were designed. They correlate with the known results of similar tasks and allow to formulate the recommendations on their use in cascade code constructions.
