Abstract:
A method is disclosed for synchronization, comprising obtaining baseband signal samples of a baseband information signal having an in-phase signal sample and a quadrature signal sample, the baseband information signal having been generated by mixing a received modulated carrier signal with a local oscillator (LO) signal having an LO frequency, the modulated carrier signal being an in-phase signal and quadrature signal having a substantially uncorrelated nature and derived from different input data sets; determining an offset frequency rotation based on an estimated residual correlation between the in-phase signal samples and the quadrature signal samples; and, deriving synchronization information from the offset frequency rotation, wherein the received modulated carrier signal is a quadrature-modulated signal with arbitrary orthogonal in-phase and quadrature signal components.

Claim (Index 1):
A method comprising:\n generating a baseband information signal by mixing an arbitrary received modulated carrier signal with a local oscillator (LO) signal having an LO frequency; obtaining a plurality of baseband signal samples of the baseband information signal having a baseband signal magnitude and a baseband signal phase; determining a cumulative phase measurement associated with the baseband signal samples using the plurality of baseband signal samples over a period of time; and applying a correction signal to compensate for an LO frequency offset of the LO frequency based on the cumulative phase, thereby reducing an effective LO frequency error to less than 100 parts per billion.
