Abstract: A communication device is provided that includes a receiver configured to receive a radio frequency signal. The communication device further includes a processor configured to determine a shift frequency based on a component radio frequency signal. The processor is configured to determine a second signal based on the radio frequency signal. The component radio frequency signal is based on the radio frequency signal and associated with a frequency related to the radio frequency signal represented in the frequency domain. The second signal is determined based on shifting frequencies related to the radio frequency signal represented in the frequency domain by the shift frequency.
