Abstract

In this thesis, a radio channel measured at 29 GHz for 5G communications is analysed and a corresponding channel model is evaluated. For this purpose, we have studied two different scenarios, where the first one represents a macrocell environment and the second one a microcell environment. Both scenarios had the same fifteen user equipment antenna locations and their main difference is the location from its base station. Indeed, these two different propagation scenarios are assumed to be static during the whole measurement.

Once the scenarios have been described, the delay spread, azimuth spread and path loss parameters from all the different paths that are received at each user equipment antenna are estimated. In order to do that, it has been considered whether those paths were on Line-Of-Sight or Non-Line-Of-Sight condition. As little research has been done at this frequency band for this innovative application, it is important to analyse and validate of those results. For that purpose, a MATLAB program has been designed for the automatic validation of those results, and at the same time, information about the channel behaviour is provided. Furthermore, these two scenarios have been analysed by implementing Keysight’s Geometric Channel Modeling Tool, where a reconstruction of the channel has been obtained.
