METHODS FOR ENSURING ELECTROMAGNETIC COMPATIBILITY OF MOBILE TELECOMMUNICATION SYSTEMS

Abstract

The subject is the process of ensuring electromagnetic compatibility in a self-organized mobile wireless network by using ultra-wideband signals with a high information capacity. The goal is to develop recommendations for the implementation of wireless mobile communication when transmitting discrete messanges over a communication channel with additive Gaussian noise. The objective is toensure stabile and reliable operation of the ultra-wideband communication system. Methods used: analytical modeling methods and thetheory of potential stability. The following results were obtained. A criterion for ensuring the requirements of electromagnetic compatibility of mobile telecommunication systems has been developed. On the basis of the theory of potential noise immunity, the possibility of stabile and interference-free operation of a telecommunication wireless system in conditions when the level of the information signal and noise have the same value is shown. The possibility of extracting a transmitted information signal from a maxture of noise and a useful signal by correlating the received abd reference signals has been proven. Conclusions. It is shown that the use of ultra-wideband signal thechnology allows for wireless cover information transmission with low radiation power. Moreover, the large base of the signal allows to ensure stabile interference-free operation of the telecommunication communication system in conditions when the level of the information signal is at or below the noise level. At the same time, the possibility of extracting a useful signal from a mixture of information binary sagnals with white Gaussian noise has been proved
