Evaluation of effectiveness of the coding and decoding algorithms in information channels realized on base of code signal feature

At present, especially urgent task is ensuring a high level of the noise immunity of digital information channels (DIC) due to the constant tightening of requirements. For this purpose, the processing of the signal is carried out while preparing it for the transmission, generally using coding stages (concatenated coding) by block codes and continuous error-correcting codes including coded modulation procedure. This allows providing the high rates of noise immunity systems for the transmission of information in channels with high interference level. A significant gain is given by application of non-binary codes. In addition, for the correct functioning of the DIC in-phase synchronous operation of all transmitter-receiver units, included in its composition, should be provided. This paper presents an analysis and evaluation of the effectiveness of implementation of DIC based on code signal feature (CSF) on the basis of the criterion proposed earlier by the authors in [1].
