Modern training courses rarely consider complex issues of modulation and coding, as well as their signal-code constructs. There are few textbooks for the implementation of modern modems and codecs. The relevance of the manual is great, since in modern communication and television systems, as well as cable networks, increasingly complex types of modulation and coding are used, which provide high noise immunity. The course methodology consists in consolidating theoretical knowledge on the examples of computer implementation of modems and codecs of modern telecommunication systems.
