| 摘 要： | 提出了一种基于滤波器组的单载波频域均衡(FB-FDE)技术的窄带干扰抑制方法,该方法在多径时延较大的地空宽带通信中具有很强的窄带干扰抑制能力。从理论上详细分析了基于滤波器组的窄带干扰抑制技术能够克服基于FFT频域均衡缺点的主要原因,并在此基础上提出了基于自适应子带合并的算法。理论分析和仿真试验均表明,该方法抑制窄带干扰能力强,运算简单,适于工程实现。

| Abstract: | A method of suppressing narrowband interference(NBI)is proposed in this paper that utilizes the single-carrier frequency domain equalization technique based on filter banks theory.This method has strong suppressing ability for NBI in the ground-air wideband communication which has larger multipath time delay.It is considered completely in theory why the NBI method based on filter banks can overcome the disadvantages of FFT method,and the adaptive subband merging is presented.Theoretical analysis and simulation experiment show that the method is practicable in engineering because it has strong suppressing ability for NBI and is simpler in computation. |
