摘要：
We present an optimal frame timing estimator for OFDM signals that utilizes both cyclic prefix (CP) and pilot carrier-aided channel estimation. Combining the periodic nature of the embedded pilot signal information with the correlation present in the cyclic prefix allows improved frame timing estimates relative to use of either one. Following a derivation of the ML estimator, a processor diagram is provided, and simulation results compare the performance of the new synchronizer with that of Sandell et al [1] that employs only the CP structure. In the present paper, we assume negligible frequency offset due to Doppler and/or oscillator frequency error.
