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.
