Synchronization signal detector and method of detection of synchronization signal

Image Number 2 for United States Patent #7092469.

The invention is a method and demodulator which detects periodic synchronization signals. The method of the invention includes multiplexing orthogonal signals in a wireless transmission into a signal stream; applying the signal stream to a synchronization signal detector which produces an output signal including detection of a unique code representing the synchronization signals within the signal stream; demultiplexing the output signal into orthogonal signals; calculating a function of the demultiplexed orthogonal signals and combining the function of each of the orthogonal signals into a combined output signal; averaging the combined output signal over a time period during which the synchronization signals repeat to produce an averaged signal; detecting peaks in the averaged signal; and synchronizing a demodulator in response to the peaks which demodulates the wireless transmission.
