FDM
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.[)
