  • Method and apparatus for detecting peaks in an optical signal using a cross-correlation filter
    Patent number: 7006206
    Abstract: A method and apparatus is provided for detecting peaks in an optical signal. The method comprises the three basic steps of: (1) sampling the optical signal to obtain sampled data containing information about the optical signal; (2) applying a cross-correlation filter on the sampled data to obtain cross-correlated data containing information about one or more peaks in the optical signal; and (3) detecting the one or more peaks in the optical signal based on the cross-correlation data. In one embodiment, the cross-correlation filter has an average value that is less than zero. The step of applying the cross-correlation filter includes reducing random noise present in the sampled data to remove quasi-dc components from the sampled data.
