Sensing-Enhanced Channel Estimation for Near-Field XL-MIMO Systems
Sensing-Enhanced Channel Estimation for Near-Field XL-MIMO Systems
Future sixth-generation (6G) systems are expected to leverage extremely large-scale multiple-input multiple-output (XL-MIMO) technology, which significantly expands the range of the near-field region. The spherical wavefront characteristics in the near field introduce additional degrees of freedom (DoFs), namely distance and angle, into the channel model, which leads to unique challenges …
