Abstract:
A method for synchronizing detection windows with a stream of phase-encoded digital data produced from a computer device, the method comprising the steps of:determining whether an individual data pulse within the stream of phase-encoded digital data occurs late with respect to a corresponding detection window;determining whether an individual data pulse within the stream of phase-encoded digital data occurs early with respect to a corresponding detection window;counting occurrences of late data pulses;counting occurrences of early data pulses;comparing the count of late occurrences of data pulses with a predetermined late threshold value greater than one;adjusting the detection windows later in time when the count of late occurrences equals or exceeds the late threshold value.comparing the count of early occurrences of data pulses with a predetermined early threshold value greater than one; andadjusting the detection windows earlier in time when the count of early occurrences equals or exceeds the early threshold value.
