Summary:
In this letter, we present timing synchronization method using two consecutive orthogonal frequency division multiplexing (OFDM) symbols which are designed to be cyclic-shifted against each other. Our approach can be viewed as an expansion of Minn's correlation methods. Using the proposed OFDM signal, however, we can estimate the timing offset without any training symbol.
