摘　　要：为了提高Ka频段移动卫星通信的传输速率,增强数据传输的可靠性,通过分析Ka频段的信道特性,建立了一种基于自适应Turbo-OFDM的Ka频段系统模型,并在不同的环境下,针对不同的自适应参数,设定了不同的控制算法进行仿真分析,结果表明,该模型在低信噪比和恶劣的环境下,能更好地提高数据传输的可靠性,在高信噪比和较好的环境下,能大大提高数据的吞吐量。In order to improve the mobile satellite communication transmission rate and enhance the reliability of data transmission in Ka band, an algorithm based on the Ka band ATC-OFDM system model is proposed. Simulation results for different environments with different adaptive parameters show that the model can better improve the reliability of data transmission in adverse environment with low SNB, and can greatly improve the data throughput in favorable environment with high SNB.
