An Interpolation-Based Frequency-Synchronization Scheme for OFDM Systems

Overview The mismatch of the oscillators in the transmitter and receiver, or Doppler shift, introduces an offset in the expected carrier frequency. In orthogonal frequency-division multiplexing (OFDM) systems, this frequency offset causes large errors in the signal values and therefore it is important to minimize this offset. This paper proposes an interpolation-based scheme for carrier frequency offset synchronization in OFDM systems.
