摘要：

An efficient timing and frequency synchronization scheme for orthogonal frequency division multiplexing (OFDM) based TETRA system is present. TETRA specifies its own preamble for timing synchronization and frequency offset estimation. Two correlators are utilized in this paper to make timing more accurately. A frequency offset estimator with adjustable parameter is proposed in time domain. According to the operation condition, set the proper range of the frequency offset estimator so that the best accuracy can be achieved. Simulation result shows that the proposed schemes exhibit good performances in the channel model defined in TETRA.
