| Abstract: | Doubly-selective fade of channel degrades the performance of orthogonal frequency division multiplexing(OFDM) system because it introduces the inter-carrier interference(ICI).An algorithm of equalization is proposed which combines iterative inter-carrier interference mitigation with the 1-tap frequency-domain equalizer,based on an analysis of ICI generation mechanism.Analysis and simulation indicate that the algorithm can suppress the ICI effectively and improve the performance of bit-error rates of OFDM system. |
