Abstract

As a promising technique for high data-rate transmission, Orthogonal Frequency Division Multiplexing (OFDM) has been considered for many emerging wireless applications due to its high spectral efficiency and robustness against frequency selective fading. However, in time variant mobile radio environment, the relative movement between transmitter and receiver resulted in frequency offset caused by Doppler frequency shifts. Therefore, the carriers cannot be perfectly synchronised. This imperfection destroys the fundamental orthogonality characteristics among subcarriers in OFDM signal. This loss of orthogonality causes intercarrier interference (ICI) to occur in addition to signal rotation and attenuation [1].
