摘要
介绍了Beyond3G的基本要求,分析了OFDM技术的特点,建立了OFDM技术应用于Beyond3G的仿真模型,对不同调制方式和不同应用信道模型进行了仿真研究。研究表明:OFDM系统可以有效克服多径干扰和多卜勒效应,能够应用于Beyond3G。
This paper introduces the basic demands on Beyond 3G and analyzes the characteristics of OFDM technology. The OFDM simulation model applied in Beyond 3G is established. According to the proposed model, the differentmodulation methods in several practical application channels are simulated. Thesimulation results indicate that the OFDM system can efficiently overcomes multi-path interference and Doppler effects and can be applied in Beyond 3G.
