Summary: One new joint frame synchronization and carrier frequency offset estimation method for orthogonal frequency-division multiplexing (OFDM) system is proposed. The same training-symbol-block (TSB) is needed for both frame synchronization and carrier frequency offset estimation. The carrier frequency offset estimation including acquisition and tracking, and acquisition can be further divided into preacquisition and fine acquisition. As soon as frequency offset acquisition finished, timing synchronization is also performed at the same time. The acquisition range is as large as one half of overall signal bandwidth. The theoretical variance error lower bound for our frequency offset tracking algorithm is also derived in this paper.
