Qualitative study of some communication systems with random signals

Abstract

This article presents a qualitative analysis of common communication systems based on random signals. The analysis is given in the context of protecting transmitted data from unauthorized access: the method of chaos shift keying and the method of chaotic modulation. As a result of the qualitative analysis presented by the time diagrams of the signals transmitted in the communication channel it was established that the chaos shift keying method presented by the COOK communication system has pauses in the transmission of information by random signals. At the same time the chaotic modulation method represented by apparatus for anti-imitation protection of controlled objects does not have pauses in the transmission of information by random signals. The principle of the energy receiver functioning for the COOK communication system and apparatus for anti-imitation protection of controlled objects were shown. It is established, that communication systems based on chaotic modulation methods are more preferred for the protection of the transmitted signals from unauthorized access than the chaos shift keying method presented by the COOK communication system
