Abstract :
A new method to correct the block timing offset in MC-CDMA system with frequency offset is proposed. Consecutive training sequences an used to acquire the initial time synchronization. The effect of the frequency offset on this estimator is analyzed. We compared this new method with Schmidl and Cox´s (1997) method (for short, SC method) through simulation in terms of estimator mean and variance, both in AWGN channel and time-varying frequency channel. Results show that the new method is better than SC´s method.
