摘要
正交频分复用(OFDM)系统是未来无线通信系统的基本应用技术之一,它即是一种多载波高效调制技术,又是一种频分复用技术,具有频谱利用率高、抗符号间干扰和抗多径衰落的优点,适合在无线信道中传输高速数据。
OFDM system is one basic technique of the future wireless communication.It is a Multi-Cartier Modulation technique with high performance.It has high utilization of frequency spectrum,good capability of countering inter-symbol interference and multi-path fading,It is also adaptive to high-rate data transmission in wireless channel.
