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.

Abstract: A communication device comprises a receiver including at least two receive antennas and configured to receive at least one reference signal of a plurality of reference signals, each reference signal being transmitted from at least one base station at a predefined reference signal transmission time; a controller configured to switch between at least two receive configurations of the at least two antennas during a reception period of the at least one reference signal; and a signal quality determiner configured to determine a parameter indicative of a first signal quality of the received reference signal for each receive configuration.
