Abstract
A method and apparatus for phase adjustment of a RF transceiver is disclosed. Based on a first local oscillator signal and a second local oscillator signal, a beat signal that indicates the frequency and phase relationship between the first and second local oscillator signals can be generated. Using the beat signal, changing phase relationship between the first and second local oscillator signals can be cumulatively taken account for using phase averaging to allow quick restoration to observation of a previously observed channel.
