Abstract :
Based on the criterion of maximum likelihood (ML), a blind carrier frequency offset (CFO) estimation algorithm for multi-user OFDM system is proposed when the demodulated data are sent to the CFO estimation module. This proposed algorithm is not optimal but it has advantages such as no cyclic prefix, low complexity. Corroborating simulations reveal its performance merits.
