Patent ID: 7319492

Claim:
A system for synchronizing a first sampled signal with an associated sub-carrier having a first sub-carrier phase and a second sampled signal with an associated sub-carrier having a second sub-carrier phase, the system comprising: a first logic circuit storing the first sampled signal and the first sub-carrier phase; a second logic circuit communicatively coupled to the first logic circuit, the second logic circuit receiving as inputs the first sub-carrier phase from the first logic circuit and the second sub-carrier phase, the second logic circuit outputting an indication of phase difference between the first sub-carrier phase and the second sub-carrier phase; a third logic circuit communicatively coupled to the first logic circuit and the second logic circuit, the third logic circuit receiving the first sampled signal from the first logic circuit and the indication of phase difference from the second logic circuit, the third logic circuit outputting the first sampled signal time-shifted according to the indication of phase difference.
