Abstract
Embodiments of the invention consist in a method of carrier synchronization, comprising determining a frequency offset estimate from a rate of change of a phase difference between a local oscillator signal and a carrier signal of a received signal; and adjusting a frequency of the local oscillator signal by the frequency offset estimate.
