Wireless time and frequency lock loop system
Abstract:
Systems and methods for wireless synchronization are disclosed. In one embodiment, a method is disclosed for synchronizing a slave device to a master device, comprising: receiving, at a local device, a master device reference signal in the form of a modulated radio frequency (RF) signal from a master device; receiving, at the local device, a master device time stamp from the master device; computing a time offset of the master device reference signal relative to a local reference oscillator signal of a local oscillator, using the master device time stamp; computing a frequency offset of the master device reference signal relative to the local reference oscillator signal; generating a local reference oscillator control signal based on the computed time offset and the computer frequency offset; and adjusting the local reference oscillator to maintain a frequency and time lock with the master device reference signal at the local device.
