Timing synchronization of wireless networks

摘要

A single wireless slave node may be in a timing virtual network (TVN) with neighboring wireless slave nodes. The single wireless slave node may store information indicative of the identity, link propagation delay, and channel signature of each of its neighboring wireless slave nodes. The single wireless slave node may repeatedly update a timing estimate based on the stored information and by performing a physical layer fast reference signal broadcast transmission and reception.

主权项

1. Non-transitory, tangible, computer-readable storage media containing a program of instructions that cause a single wireless slave node running the program of instructions in a timing virtual network (TVN) with neighboring wireless slave nodes to:
store information indicative of an identity, link propagation delay, and wireless channel impulse response of each of its neighboring wireless slave nodes; repeatedly perform a physical layer fast reference signal broadcast transmission and reception; and repeatedly update a timing estimate based on the results of the repeated broadcast transmission and reception and the stored information.
