Abstract
A method and apparatus for identifying a search window of carrier-frequency-offset-corrected samples in which a first intermediate signal from a demodulator does not exceed a predetermined threshold, convolving a second intermediate signal from the demodulator within the search window with a predefined pattern to provide a convolution result, determining if an absolute peak of the convolution result exceeds a preamble pattern confirmation threshold, in response to the absolute peak of the convolution result exceeding the preamble confirmation threshold, confirming a preamble pattern detection event to provide a confirmed preamble pattern detection event of a confirmed preamble pattern, and receiving a signal including the confirmed preamble pattern to provide a received digital signal extracted from the signal.
