Abstract
A processing platform in illustrative embodiments comprises one or more processing devices each including at least one processor coupled to a memory. The processing platform is configured to extract channel features of a wireless channel of a wireless system from channel state information characterizing a radio geometry of the wireless channel, to generate a forward charting function that maps the extracted channel features to a channel chart characterizing a representational spatial geometry of the wireless channel, and to utilize the channel chart to estimate at least one position-related characteristic of one or more wireless devices in an actual spatial geometry of the wireless channel. Generating the forward charting function illustratively comprises performing an unsupervised learning process to learn the forward charting function from the extracted channel features. The channel chart is illustratively configured to preserve local geometry of multiple spatial locations associated with the extracted features in the actual spatial geometry of the wireless channel.
