Inter-Carrier Interference Compensation for Zero Padding OFDM

Zero Padded (ZP)-OFDM has attracted a lot of attention as an efficient technique to improve the performance in severe frequency selective channels, and many works were devoted to the equalization methods of ZP-OFDM in static channel models. In this paper, we propose the ICI compensation method corresponding to ZP-OFDM in the time and frequency selective channel. In the proposed method, the channel variation within one OFDM symbol is assumed to be linear to reduce the computational complexity. Simulation results show that the proposed method improves the performance in the frequency and time selective channels.
