In this paper, a novel frequency synchronization algorithm for a new modulation scheme named time domain and frequency domain united orthogonal frequency division multiplexing (TFU-OFDM) is introduced. The frequency synchronization method has two-steps, which joints time and frequency domain estimation based on PN sequences and pilots. We utilize the PN sequences as guard intervals in time domain to achieve the first-step estimation and the second-step is realized by the pilots in data blocks in frequency domain. The simulation results and analysis show that the proposed frequency synchronization method could achieve fast and reliable synchronization and sufficient precision, and provides excellent performance for TFU-OFDM systems.
