Abstract :
Blind synchronization algorithm is developed for estimating jointly timing and frequency offset of OFDM signals transmitted through a frequency-selective fading channel. The proposed estimator exploits the second-order cyclostationarity of received signals. As a blind estimator, the information of impulse response of channel is not required. The performance of the estimator is evaluated through computer simulations
