A well-known problem of OFDM is its sensitivity to carrier frequency offset which leads to inter-carrier interference (ICI) in the OFDM symbol. This ICI causes severe degradation of the BER performance of the OFDM receiver. In this paper, we propose a new ICI cancellation algorithm which estimates frequency offset at the time-domain by using cyclic prefix-independent component analysis (CP-ICA) method to the received subcarriers phase rotation. This algorithm is based on a statistical blind estimation method, which mainly utilizes the eigenvalue decomposition (EVD), rotating phasor and the 4th cumulants.
