摘　　要：比较了FDM、OFDM以及FBMC的频谱使用效率。详细分析了OFDM信号带外辐射较大的原因,探讨了FBMC抑制带外辐射的机理。借助MATLAB对OFDM与FBMC信号的频谱进行了仿真,结果表明:FBMC有效地减小了带外辐射,提高了通信系统的频谱使用效率。Spectrum efficiency of FDM,OFDM and FDMC was compared.The reason of the high radiation outside the OFDM signal band is analyzed in detail,the principle of suppressing external radiation is discussed for FBMC signal.The spectrum of OFDM and FDMC signal is simulated by MATLAB,simulation results show that the FBMC effectively reduces the radiation outside the band and improves the spectral efficiency for communication system.
