摘要
从理论上研究了以OFDM和FMT为代表的多载波系统载波抗频偏性能,并通过Matlab进行仿真和验证,比较了它们的ICI,ISI,有用信号功率、功率损减因子等抗频偏性能。重点分析了矩形窗滤波器下FMT系统的抗频偏参数。理论分析与仿真证明,滤波多音调制系统有着比正交频分复用系统更好的抗载波频偏能力。
The carrier anti-offset performanc of multi-carrier system represented by OFDM and FMT is researched theoretically.The anti-offset performances,such as ICI,ISI,useful signal power and power impoverishment factor was compared through simulation and verification with Matlab.Some anti-offset parameters of FMT were analysised.Both theoretical analysis and simulation show that the filtering multitone modulation system has more the ability of anti-carrier frequency offset than orthogonal frequency division multiplexing system.
