Abstract
A method and apparatus for automatic frequency control in a receiver of a wireless device, the method determining a channel estimation for a received signal; calculating a signal to noise ratio for the channel estimation; applying a weighting factor determined based on the calculated signal to noise ratio for the channel estimation to the channel estimation to create a weighted channel estimation; and supplying the weighted channel estimation to a voltage controlled oscillator.
