The paper investigates the influence of the frequency and time offset on the in-symbol and inter-symbol interference in OFDM communication systems.
A method is proposed for blind estimation of the offsets, which uses the cycle stationarity introduced in the information signal. A possibility is considered to accomplish the estimation, using the virtual subcarriers.
