Query: Bayesian Joint Synchronization and Localization Based on Asymmetric
  Time-stamp Exchange   In this work, we study the joint synchronization and localization (sync&loc)
of Mobile Nodes (MNs) in ultra dense networks. In particular, we deploy an
asymmetric timestamp exchange mechanism between MNs and Access Nodes (ANs),
that, traditionally, provides us with information about the MNs' clock offset
and skew. However, information about the distance between an AN and a MN is
also intrinsic to the propagation delay experienced by exchanged time-stamps.
In addition, we utilize Angle of Arrival (AoA) estimation to determine the
incoming direction of time-stamp exchange packets, which gives further
information about the MNs' location. Finally, we employ Bayesian Recursive
Filtering (BRF) to combine the aforementioned pieces of information and jointly
estimate the position and clock parameters of MNs. The simulation results
indicate that the Root Mean Square Errors (RMSEs) of position and clock offset
estimation are kept below 1 meter and 1 ns, respectively.
