  • Closed loop sub-carrier synchronization system
    Publication number: 20040174935
    Abstract: A system and method for synchronizing sub-carriers in a signal processing system. Various aspects of the present invention may comprise method steps and structure that receive a sampled signal. Various aspects may produce a synchronization signal based on the sampled signal. Various aspects may generate and store a cropped version of the received sampled signal. Various aspects may read a cropped sampled signal from memory that corresponds to the received sampled signal. Various aspects may generate a restored sampled signal by adding samples to the cropped sampled signal read from memory. Various aspects may, based on the synchronization signal, output the restored sampled signal coarsely synchronized to the received sampled signal. Various aspects may determine a phase difference between the output restored sampled signal and the output received sub-carrier. Various aspects may adjust the phase of the restored sampled signal in response to the determined phase difference.
