ABSTRACT:
Methods and apparatus for resolving frequency errors in a wireless device transitioning from a first communication network to a second communication network are disclosed. The methods and apparatus effect reception of a first and second channels from the second communication network where the first channel has known characteristics. The first channel is then decoding for a prescribed period and an initial frequency error value is determined based on the decoding of the first channel. A digital frequency rotator is then adjusted based on the initial frequency error value for purposes of decoding the second channel. The second channel is then decoded using the digital frequency rotator as adjusted based on the initial frequency error value, without further calculation of the frequency error.
