Аннотация
The article considers the basic principles of constructing a system of error-correcting coding and decoding of high-precision iterative codes. For the practical implementation of methods and algorithms of high-precision iterative, a codec based on a programmable logic integrated circuit has been developed, which can be used for coding and high-precision iterative decoding block, convolutional and compositional codes in digital television systems, digital data transmission and satellite communications. The model makes it possible to construct the probabilistic-energy characteristics of high-precision iterative codes with their various code constructions, conducts research and analysis to determine the efficiency and basic properties of these codes. A new method for compositional coding of high-precision iterative codes (compositional code) has been developed.
