Abstract
The article analyzes the approaches to the mathematical modeling of mobile systems in millimeter wavelength range. For implementation of wireless communication concepts in the millimeter range, the use of photonic methods for the formation and transmission of signals through optical lines using the technology Radio over Fiber is considered. Considered the architecture of the mobile network using Radio over Fiber technology. The optical heterodyne noise used to generate radio signals is analyzed. The mathematical analysis of the radio link energy budget components in the millimeter range is conducted on the basis of the fundamental physical aspects study affecting the value of noise, loss and amplification of the signal. Comparison of signal to interference ratio, signal to noise ratio, the probability of transmitting information radio signals through reflected paths. From the analysis of the components of the radio link energy budget in the millimeter range, it follows that it is necessary to take into account in the models the interference noise as well as the noise associated with the generation method, signals emission, for example, in phased array antennas, and also to take into account the effects of molecular absorption (repeated radiation) in the atmosphere and the reflection effects of signals in the urban scenario. A quasi-optical model of cone-shaped radiation of an antenna is possibly more suitable for calculating noise disturbances and signal loss in multipath propagation models, taking into account multiple reflections and diffractions, as well as absorption in various media.
