Patent ID: 8923778

Claim:
A method for providing automatic frequency correction (AFC) in a wireless communication device having at least two transceivers, the method comprising: estimating a first frequency error between a first received signal corresponding to a first transceiver and a shared reference clock signal; estimating a second frequency error between a second received signal corresponding to a second transceiver and the shared reference clock signal; determining a first AFC for the first frequency error by selecting a type of the first AFC that provides at least one of: (a) an adjustment to a shared synchronization signal; (b) an adjustment to an exclusively local synchronization signal; and (c) a de-rotation of a first carrier signal corresponding to the first received signal; in response to selecting the type of the first AFC that provides an adjustment to at least the shared synchronization signal, calculating a second AFC using values corresponding to (a) the second frequency error and (b) the adjustment to the at least the shared synchronization signal provided by the first AFC; in response to not selecting the type that provides an adjustment to the shared synchronization signal, calculating the second AFC utilizing values corresponding to the second frequency error, wherein the second AFC is not calculated based on an adjustment associated with the first AFC; and synchronously applying (a) the determined first AFC to compensate for the first frequency error and (b) the second AFC determined using the second frequency error.
