In this paper, a blind OFDM system parameters estimation method for software defined radio (SDR) is proposed. This method sequentially estimate the sampling frequency, the number of subcarriers, the CP length as well as the timing and frequency offset in OFDM systems. The blind estimation is based on a combination of the cyclostationarity test and correlation. Monte Carlo simulation is employed to test the performance of the individual estimators as well as the whole estimator.
