Zusammenfassung: | Clock synchronization and ranging over a wireless network with low
communication overhead is a challenging goal with tremendous impact. In this
paper, we study the use of time-to-digital converters in wireless sensors,
which provides clock synchronization and ranging at negligible communication
overhead through a sawtooth signal model for round trip times between two
nodes. In particular, we derive Cram\'{e}r-Rao lower bounds for a
linearitzation of the sawtooth signal model, and we thoroughly evaluate simple
estimation techniques by simulation, giving clear and concise performance
references for this technology. |
