摘要 文章提出了子信道功率控制在Ka频段卫星通信信道DT-OFDM系统中应用的方案,给出了系统模型的组成和差分软检测方法,并根据系统模型进行了仿真。仿真结果表明应用子信道功率控制的DT-OFDM方案与传统的CC-OFDM方式相比,在10^(-3)误码率时能得到4dB的信噪比增益。 A subehannel power controlled differential Turbo coded OFDM （DT-OFDM） system for satellite communications in Ka band was proposed. The configuration of the system model and the differential detection method is presented. Simulation is progressed based on the system model. Results show that, the proposed scheme can give 4dB gains in SNR at the BER of 10^-3, compared to conventional CC-OFDM.
