The Route from Synchronization to Desynchronization of Chaotic Operating Circuits and Systems

In a world of an ever increasing information-trafficking, ultra wideband information transmission, as well as security are main issues. Chaotic oscillators inherently possess these two properties. Consequently, chaotic transmitter-receiver synchronization emerges as a key-topic in networked communication. The issues of synchronization robustness and synchronization stability are of great importance, if one means to turn in advantage properties of chaotic operating circuits and systems. As a result, not only synchronization accomplishment but also the ways a system desynchronizes is of great importance, if not crucial; however, these are not, usually, thoroughly studied. In this contribution a short overview of experimental work dedicated to the ways chaotic-synchronized communication systems desynchronize, is provided.
