More Information
Summary:The invention is a method of synchronizing a digital telemetry receiver to a digital telemetry transmitter. The method includes the steps of initializing the sampling period of the receiver, measuring the detection time of each signal event detected by the receiver relative to a time window based on the sampling period, accumulating statistics representing the detection times of each of the events, and calculating a refined sampling period based on a linear regression fit of the actual detection time of each event.
