• A Signature Based Approach Towards Global Channel Charting with Ultra Low Complexity

  Channel charting (CC) is an unsupervised learning method that uses channel information (CI) to extract a low-dimensional embedding (i.e., the chart) that preserves geometrical structure of physical space of user equipments (UEs), which facilitates a broad distance-based or location-based applications, such as handover, indoor localization, beam management, pilot management, and so on [1].
