摘　　要：多径衰落信道中进行高速率数据传输,容易造成符号间干扰(ISI)。新兴的多载波技术滤波多音(FMT)调制具有子信道频谱严格约束的特性,在有效克服信道间干扰(ICI)的同时克服信道造成的ISI。比较了在多径衰落环境中,滤波多音调制性能,分析多径衰落对系统性能的影响,探讨FMT技术在无线领域的应用环境及可行性。Inter-symbol interference (ISI) damages the quality of high rate data transmission in decaying multipath channel. A new multicarrier technique called filtered multitone(FMT) with high level spectral containment is negligible to inter-channel interference(ICI) and also to ISI introduced by wireless channel. Simulation results present the performance of FMT system in decaying multipath channel, form which the possibility of applying FMT in wireless environment is discussed.
