Query: A Fisher Information Analysis of Joint Localization and Synchronization
  in Near Field   In 5G communication, arrays are used for both positioning and communication.
As the arrays become larger, the far-field assumption is increasingly being
violated and curvature of the wavefront should be taken into account. We
explicitly contrast near-field and far-field uplink localization performance in
the presence of a clock bias from a Fisher information perspective and show how
a simple algorithm can provide a coarse estimate of a user's location and clock
bias.
