摘要 OFDM(正交频分复用)和M IMO(多输入,多输出天线)是未来宽带无线通信的主流技术,OFDM技术是一种正交频分复用方式,在这种方式下通信系统的频谱利用率得到大大提高,M IMO技术是一种多输入多输出天线技术,它可以成倍的提高无线通信系统的信道容量。在此主要介绍了OFDM和M IMO的理论基础,以及当前的应用和未来的发展前景。 OFDM(Orthogonal Frequency Division Multiplexing) and MIMO(Multi-inputs Multi-outputs) are the mainstream of wireless communications technology.OFDM technology is a special kind of frequency division multiplexing.To improve the spectrum utilization of the system,MIMO technology is a more antenna technology and improves the communication channel capacity of system.This paper mainly introduces OFDM and MIMO'S theoretical foundation,current applications and development prospects.
