Unsupervised Channel Charting with Channel State Information Using ULA and UCA Antenna Models in 5G Network

Abstract

Channel charts are a map of the radio geometry that surrounds the base station and they are generated in an unsupervised manner from the received channel state information. In this work, we generate channel charts for two different antenna types for three different base station configurations. The method for generating the charts is explained, after which the results are shown and analysed.
