摘要：

Orthogonal Frequency Division Multiplexing (OFDM) is a modern high data rate modulation technique for wireless communication systems. Due to loss of orthogonality of subcarriers Intercarrier interference occurs. In this paper the performance of the proposed time-domain equalization technique is compared with the existing Frequency domain equalization technique In Frequency domain equalization a correlative polynomial is used in the frequency domain to suppress the ICI In Time domain equalization technique, a window function is proposed in equivalent to the Correlative polynomial used in the frequency domain. MATLAB simulation of the proposed technique shows that the time domain windowing scheme achieves better performance in ICI suppression compared to the correlative coding technique. Time domain windowing technique proposed in this paper, offers better carrier to interference ratio (CIR) and BER is reduced compared to the correlative coding method.
