摘要
通过分析正交频分复用技术(OFDM)的原理和系统实现方法,详细讨论了在宽带无线接入技术中的三种基于OFDM的高速无线传输技术:VOFDM,WOFDM和flash-OFDM,并比较了它们的性能特点,指出了在高速无线传输领域中OFDM技术将会得到广泛应用的必然趋势。
First the principle and realizing method of system about OFDM is introduced in this paper. Then it analysed three kinds of superspeed wireless transmit technology based on the OFDM in the broadband connect field, they are VOFDM, WOFDM and flash-OFDM, discussed their function characteristics. Finally, it showed the development of OFDM technology in the future.
