摘要
采用ADS仿真软件对OFDM系统和SC-FDE系统进行了仿真实现,对这两个系统的结构和性能进行了对比,分析了两个系统对功率放大器的要求。仿真结果表明,综合这两个系统优点的双模式系统将会是一个技术上更为优越的宽带传输方案。
With help of ADS software tool, the OFDM system and SC - FDE system are implemented and simulated. Their structures and performances are compared. Their requirements for the lineafity of power amplifiers are analyzed. The simulation results show that the dual mode system based on the two systems will be the better broadband communication system.
