Abstract
Apparatuses, methods and systems for mitigating carrier offset of a received signal are disclosed. One embodiment of a receiver includes a controller operative to determine that a communication signal being received is from a desired transmitter, and to determine a carrier offset correction based on prior reception of communication signals from the desired transmitter, comprising retrieving a carrier offset of the desired transmitter from one or more stored carrier offsets based on previous communication with the desired transmitter and a temperature of the receiver. The receiver further includes a receiver chain operative to receive the communication signal from the desired transmitter, and to generate a carrier offset corrected received signal based on the retrieved carrier offset by applying the carrier offset correction to the received communication signal. The receiver is operative to synchronize to the carrier offset corrected received communication signal.
