摘要 该文提出了将Turbo码与OFDM调制、差分检测技术相结合 ,分析了这种差分Turbo OFDM体制在短波数据通信中的应用可能。该体制具有较高的频率利用率 ,可有效地抑制短波信道中多径时延、频率选择性衰落、人为干扰与噪声带来的不利影响。仿真结果显示该体制提高了短波信道上数据通信的误码性能。 A differential Turbo OFDM scheme with the combination of Turbo codes,orthogonal frequency division multiplexing (OFDM) modulation and differential detection is presented in this paper.The application of differential Turbo OFDM in high frequency (HF) data communication is investigated.This new scheme has the advantages of high spectrum efficiency and suppression of multipath spread,frequency selective fading,jamming and noise.Simulation results show that B performance can be improved by this scheme in HF data communication.
