Abstract
Apparatuses, methods and systems for mitigating carrier offset of a received signal are disclosed. One embodiment of a receiver includes a receiver chain operative to receive a communication signal from a desired transmitter, and a controller operative to determine a carrier offset correction based on prior reception of communication signals from the desired transmitter. The receiver chain is operative to generate a carrier offset corrected received signal by applying the carrier offset correction to the received communication signal, and a correlation processor operative to correlate the carrier offset corrected received communication signal with a known sequence.
