摘要

提出了一种在时域差分调制解调OFDM系统中跟踪载波频偏的新方法。与现有方法相比，该方案具有更高的带宽利用率和更容易实现的特点。在瑞利衰落信道中的仿真结果表明，该频率跟踪方案可以在较低信噪比条件下稳健地工作。

A novel carrier frequency tracking scheme for time domain differential OFDM

We develop a novel scheme to track carrier frequency offset in time domain differential modulation and demodulation OFDM systems. Compared with existing methods, this scheme is more bandwidth efficient and easier to implement. Simulation results in the Rayleigh fading channel show that this frequency tracking scheme can work robustly under relatively low SNR conditions.
