Abstract

It is an efficient technique to suppress the narrowband interference based on transform domain. For the problem of narrowband interference suppression ,this paper proposes a method, which uses estimation of parameters of narrowband interference based on FFT to estimate centre frequency and bandwidth very well, and then the original signal is reconstructed accurately by processing the spectrum and interpolation compensation in narrowband interference bandwidth. Simulation results support the efficiency of the method on computer with Matlab.
