%X A combined time and frequency acquisition algorithm for OFDM systems is derived in this paper. The proposed technique estimates the symbol beginning and the fractional frequency offset with the periodicity of Cyclic Prefix (CP), and simultaneously achieves the frame synchronization and the integral frequency offset correction based on differential pilot subcarriers in the first symbol of a transmission frame. Simulation results in MW/SW channels indicate the accuracy and practicability of this approach.
