Abstract

A comparative analysis of existing cascade coding schemes and digital modulation methods in the general information processing system has been carried out. Methods of encoding, in particular, turbo codes, in their capabilities are quite close to the bandwidth of the channel. It was found that classical cascading codes and their modifications are somewhat inferior to the turbo codes on the level of energy gain, but at the same time they are more simple in terms of practical implementation.
