Frequency offset
In radio engineering, a frequency offset is an intentional slight shift of the broadcast radio frequency (RF), to reduce interference with other transmitters. Carrier frequency offset arises from mismatches between the received signal's carrier frequency and the receiver's local oscillator, often due to synchronization errors and Doppler shifts.
