WebAccording to the conventional method, CFO/SFO are corrected in the frequency domain, relying on a reference signal embedded in the received signal. One of the major drawbacks of this frequency-domain method is the inter carrier interference (ICI) introduced due to CFO, which destroys the orthogonality between subcarriers in the OFDM system.

Carrier frequency offset (CFO) is one of many non-ideal conditions that may affect in baseband receiver design. In designing a baseband receiver, we should notice not only the degradation invoked by non-ideal channel and noise, we should also regard RF and analog parts as the main consideration. Those non-idealities include sampling clock offset, IQ imbalance, power amplifier, phase noise and carrier frequency offset nonlinearity.
