A synchoronization algorithm for expanded time and frequency OFDM system

In this paper, we gave a brief discussion of the expanded time and frequency OFDM (ETF-OFDM) system and its traditional synchronization method (the Schmidl's method). And then we present a rapid frame and symbol synchronization algorithm in this system for just detecting one training symbol instead of two training symbols in Schmidl's method. The algorithm has low calculation complexity and outperforms conventional synchronization methods.
