Abstract

This study is devoted to estimating the allowable angular separation between devices operating in ultra-dense radio access networks in the millimeter frequency range, for the subsequent formation of a three-dimensional radiation pattern with optimal characteristics by the base station antenna array. The content of this work can be divided into two parts. In the first part of this work, a mathematical formalization of the number of radio emission sources estimation and their angular coordinates is given. Based on the presented mathematical model and the developed simulation program, in the second part of the work, the study and determination of the accuracy characteristics of the angular separation of devices depending on interference in the scenario of diagram formation of ultra-dense radio access networks when devices use the combined azimuth and elevation measurement algorithm are carried out.
