Building a model of information signal propagation in a real electromagnetic communication channel

Abstract

Abstract Modern organizations are characterized by a large volume of various information, both electronic and telecommunications. Therefore, it is important to have high-quality access to switching nodes that provide access to all important communication lines. In Russia, where the distances between localities are huge and the quality of land lines leaves much to be desired, the best solution to this problem is the use of satellite communication systems. To date, a large number of methods for modeling satellite communication channels are known. According to the estimates of computational complexity of the above methods, the running time of the simulation algorithms remains unacceptable. There fore, it is relevant to develop new modeling methods that differ from the known methods that have these estimates with their practical reduction. The main result of the research can be formulated as the development of qualitatively new methods for modeling the satellite communication channel, which will allow us to more fully consider the electrodynamic picture of signal propagation in the channel, take into account all errors and correct them in the future when designing a real channel. The developed models will allow us to evaluate the noise immunity of the signal in the channel, investigate the signal-to-noise ratio, effects in the troposphere and ionosphere during signal transmission, and solve the problem of signal propagation delay.
