Frequency offsets in OFDM systems lead to an inter-carrier interference (ICI). In this report, we propose a time-domain inter-carrier interference canceler (ICIC) and then evaluate its performance. The advantages of time-domain ICICs are a reduction of hardware complexity and a fast processing speed. The simulation results confirm that the time-domain ICIC can compensate frequency offsets as well as Rayleigh fading fluctuations. Furthermore, it shows a high performance compared to that of the channel estimation based on pilot symbols. We also propose a dual-channel time-domain ICIC. This also compensate frequency offsets but it can reduce BERs by 2~dB at BER $=10^{-3}$ and $K=10$~dB compared to the time-domain ICIC. |
