Techniques for compensating for frequency offset of a frequency used in a translation of a signal from a first band to a second band may include using a frequency reference signal located in a different band from an information-bearing signal, where the different band may be a guard band. The frequency reference signal may be offset from a particular frequency, which may be a center frequency, of the information-bearing signal by a known amount. The frequency reference signal may be received by the transmitting station, a frequency offset may be derived, and the frequency offset may be used to pre-compensate further transmitted signals. At another station, the received frequency reference signal may be used to lock a local oscillator for demodulation and/or transmission of the information-bearing signal based on the known offset of the frequency reference signal from the frequency of the information-bearing signal.
