  • System for increasing digital data demodulator synchronization timing resolution using training sequence correlation values
    Patent number: 7039139
    Abstract: A demodulator for demodulating digital data includes a receiver for receiving a digital data signal, a determining device to determine if a fractional sample delay added to a demodulator's symbol sampling timing would improve synchronization timing, an implementing device implementing the fractional sample delay if the determining device determines that a fractional sample delay would improve the demodulation synchronization timing, and a demodulating device for demodulating the digital data signal. A method for demodulating digital data includes the steps of receiving a digital data signal, determining if a fractional sample delay added to a demodulator's symbol sampling timing would improve synchronization timing, implementing the fractional sample delay if it is determined in the determining step that a fractional sample delay would improve the demodulation synchronization timing, and demodulating the digital data signal.
