The peculiarity of signal-coded-construction with higher stability of fading in decameter channel

Abstract

The signal-coded-construction with higher stability of fading is are presented. The base of this construction is sequential (mono-carrier) transmission-method, turbo-trellis-coded-modulation and high specific keying rate. The base-peculiarity of this signal-coded-construction is time-diversity of code-symbols. For decoding the iterative procedure is used. Theturbo-decoder consists of two maximum a posteriori decoding, those a priory knowledge through pseudo-random interleaver are exchanges. The probability-performance, those findings by the use of imitation-modeling are presented. These performance confirm the efficiency of introduced method.
