摘　　要：提出了Ka频段LMS信道中的Turbo-OFDM技术,进行了Ka频段卫星通信信道特性分析及LMS信道模型研究,并在Chun Loo提出的Ka频段LMS信道模型的基础上建立了Turbo-OFDM系统模型,仿真结果表明该技术性能良好。A Turbo coded OFDM （ Turbo - OFDM ） technique is proposed for Ka - band land mobile satellite communication channel. The propagating characteristics of Ka - band satellite communication channel are discussed and LMS channel models are constructed. According to the Ka - band LMS channel model presented by Chun Loo, A Turbo - OFDM system model is constructed, and its performance is analyzed. The results show that the technique is good in performance.
