INTERFERENCE MODELING OF MILLIMETER-WAVE CELLULAR COMMUNICATIONS SYSTEMS
Journal Title: Телекомунікаційні та інформаційні технології - Year 2018, Vol 103, Issue 3
Abstract
To implement the bandwidth requirements for mobile communication systems of the fifth generation, it is assumed to use the millimeter wavelength range. However, the use of this range is significantly different from the lower-frequency radio resources, which are used in modern communication systems, for example, from the decimeter range. The unique properties of the millimeter wave propagation can fundamentally change approaches to network planning, calculating interference noise, coverage size, evaluating communication quality, required signal power and other parameters that affect network performance. This paper presents mathematical models of interference noise, taking into account the high directivity of the transmitting antenna, molecular absorption, blocking high-frequency radiation based on stochastic geometry. Mathematical modeling of mobile communication systems in the millimeter range is an ongoing research process. The creation of accurate models of such systems is important for the further development of the mobile industry and other telecommunication technologies in the millimeter and terahertz ranges. In the work, the ratios for the signal/interference i are calculated depending on different antenna aperture angles and different distances between the control receiver-transmitter pair for the two-dimensional model. And also the signal/noise molecular absorption, which, as suggested by modern studies, must be taken into account in the analysis of interference. The approaches to radio channel modeling presented in this article can be implemented to increase the efficiency of using the millimeter-wave energy and frequency resources, as well as to select the best methods of multiplexing, modulating radio signals, and calculating the energy coverage of fifth-generation cellular networks.
