The features of using noise resistant encoding for protection from errors in digital data transmission channels
with phase modulation have been analyzed. The building principles and encoder and decoder schemes of turbo-code were
observed. The digital data transmission system with outer and inner turbo-encoder has been developed. The
recommendations to type and structure of cascade encoder components have been given. Analytical relationships and
research results describing bit error probability of cascade turbo-encoder components are represented. By using simulative
modeling tools Matlab-Simulink the basic characteristics and features of digital transmission channel with cascade
turbo-encoding and digital phase modulation were researched. The energy benefit gained by using cascade structures has
been defined.
