ABSTRACT:
In an apparatus and method for detecting a preamble in a message a shorter initial average is used to estimate the peak position peak symbol duration, and then the number of subsequent delay stages is reduced to 1 per symbol where the chosen peak position is stored along with the corresponding intermediate detection value. At the output, a weighting function is applied to eliminate detection values inconsistent with a symbol-spaced signal output.
