代码说明:

  正交频分复用(OFDM)是一种特殊的多载波传输技术。它可以有效地对抗多径衰落,能够以很高的频谱利用率来实现高速数据传输。分析介绍了OFDM系统的基本原理及系统性能,以Matlab为开发平台,仿真了OFDM系统的误码率,仿真结果表明OFDM系统在较低信噪比下也具有较好的性能(Orthogonal Frequency-division Multiplexing(OFDM) is a special kind of multi-cartier transmission technology. It can effectively overcome multi-path fading and increase the spectral usage efficiency to implement high-speed data transmission. This paper analyzes the basic principle of OFDM system and system performance, and simulates the Bit Error Rate (BER) of OFDM system on the platform of Matlab. The simulation results show that the OFDM has a good performance.[)

    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.)
