码分多址(CDMA)技术作为第三代移动通信系统的核心技术，具有容量大、抗干扰能力强等优点。然而,传统的CDMA系统属于窄带扩频系统,它的数据速率比较低,不能胜任新一代移动通信系统 （beyond 3G）高速数据通信的需要。而多载波传输技术－正交频分复用（OFDM），作为后三代移动通信的核心技术，则具有高数据速率传输的特点。(Code Division Multiple Access (CDMA) technology as the third generation mobile communication system' s core technology, high capacity, anti-interference ability and so on. However, the traditional narrow-band CDMA system is spread spectrum system, and its relatively low data rate, can not do next-generation mobile communication systems (beyond 3G) high speed data communication needs. The multi-carrier transmission technology- orthogonal frequency division multiplexing (OFDM), after three generations of mobile communications as a core technology, the high data rate transmission characteristics.)
