Abstract
A method and apparatus is provided for detecting a pulse in a signal. In one aspect of the invention, a method comprises digitizing the signal into a plurality of samples; repeatedly convolving each one of at least a portion of the buffered samples R times, wherein R>1; and detecting the received signal's center of energy from the convolution results. In a second aspect, an apparatus comprises a analog-to-digital converter capable of digitizing the received signal to produce a plurality of samples; a convolution circuit, including a matched filter for convolving the digitized signal at a second sampling rate; a buffer capable of storing the samples and serially outputting each of the samples R times, where R>1, to the convolution circuit; and a detector for detecting the digitized signal's center of energy from the output of the convolution circuit.
