Abstract

Ensuring a high level of information reliability is one of the most important tasks of the synthesis of digital transmitting systems for various applications. In this paper it is suggested to use the code tag-based encoders and decoders (codecs) with distributors on multidrop delay lines (MDL) for improving the reliability of the information digital transmitting systems with QAM/COFDMmodulated signal; the benefits of the principle of self-synchronization while substantially reducing the guard interval in the structure of the transmitted signals are described; a possibility of excluding the analog signals in the channel is shown.
