System and method for data sequence correlation in the time domain

An apparatus for synchronizing a predetermined repeated data sequence contained in a first data signal at a first sample rate with the same predetermined repeated data sequence contained in a second data signal at a second sample rate in a data communications device, comprising:

• a first logical circuit configured to reduce the first sample rate of the first data signal to a predetermined correlation sample rate, thereby creating a first reduced data signal;
• a second logical circuit logic configured to reduce the second sample rate of the second data signal to the predetermined correlation sample rate, thereby creating a second reduced data signal;
• and
• a third logical circuit logic configured to determine a sequence offset between the predetermined repeated data sequence contained in the first reduced data signal and the predetermined repeated data sequence contained in the second reduced data signal.

An apparatus for synchronizing a predetermined repeated data sequence contained in a first data signal at a first sample rate with the same predetermined repeated data sequence contained in a second data signal at a second sample rate in a data communications device, comprising:

• means for reducing the first sample rate of the first data signal to a predetermined correlation sample rate, thereby creating a first reduced data signal;
• means for reducing the second sample rate of the second data signal to the predetermined correlation sample rate, thereby creating a second reduced data signal;
• and
• means for determining a sequence offset between the predetermined repeated data sequence contained in the first reduced data signal and the predetermined repeated data sequence contained in the second reduced data signal.
