Evaluation Criteria of Information Systems Interference Immunity
S. F. Babak · The Advanced Science Journal · 2014
Abstract: This article looks at quantitative measures of conformity degree of received and transmitted information messages, selected depending on message nature, and defines main approaches to assessment of information systems interference immunity. Author analyzed peculiarities of information receiving depending on signals purposes on stages of signal detection, sorting out of signals and message recovering. It is shown that the basis of all methods of improving information systems interference immunity is the use of certain differences between useful signal and interference. Demonstrated criteria for evaluation of information system interference immunity allow, at system designing stage, to consider the necessity of preliminary signal processing, selection of message transmission techniques, increase of transmission time, use of special interference-resisting codes, construction of interference-resisting receivers etc.
