1. Discussion Topics
   1. [Algorithm] First^* algorithm [1] to achieve spatiotemporal synchronization with multistatic distributed arrays:
      1. Parameters: 3D position, 3D orientation, clock time offset
      2. Scenario: line-of-sight channels between 2 anchors and 2 agents
      3. Method: Particle-based Loopy Belief Propagation

1. Outlook:
   1. 1. Extension to NLoS channels.
      2. A probabilistic model for spatiotemporal synchronization.
      3. The new model demands adaptations of the standard draft document on Overleaf.
      4. [Bounds] The Cramér—Rao bounds are largely derived on paper but need to be entered in the standard draft document.
      5. [Simulation] The Cramér—Rao bounds need to be implemented again to reflect the new model.
      6. [Modeling] Further temporal parameters (carrier frequency offset, carrier phase offset) need to enter the temporal state. Joint environment mapping may be an extension to multipath channels.
