6 ConclusionsWe have proposed a burst transmission technique using OFDM modulation for the payload transmissionand single carrier training data. The proposed synchronization algorithms come close tothe theoretical optimum and provide a means to devise low complexity per{burst demodulationof digital data in wireless networks. Besides its simplicity, its main advantage is that the samestrategy may be used for single carrier modulation, as well.AcknowledgementsThe anonymous reviewers helped to greatly improve the quality of the presented material.6
