This paper proposes a novel frequency-calibration approach based on an adaptive neural-fuzzy inference system (ANFIS). In normal mode, an oven-controlled crystal oscillator (OCXO) is steered by integrating a time-interval counter, a fuzzy controller, a digital-to-analog (D/A) converter, and other components such that its frequency can follow a primary cesium atomic clock. In addition, under the effects...
A new scheme of frequency calibration based on adaptive neural-fuzzy inference system (ANFIS) is proposed in this paper. In normal mode, an oven- controlled crystal oscillator (OCXO) is steered by integrating time interval counter (TIC), fuzzy controller, D/A converter, etc., such that its frequency can follow a primary cesium atomic clock. In addition, the ANFIS is applied when the system enters...
A new scheme of remote frequency control based on the IEEE 1588 standards, a precision time synchronization protocol (PTP) is proposed in this paper. A remote oven-controlled crystal oscillator (OCXO) is steered by integrating the PTP system, fuzzy controller and D/A converter, such that its frequency can follow a primary cesium atomic clock used as the master clock of the PTP system. Experimental...
