Robust DFT with high breakdown point for complex-valued impulse noise environment
Igor Djurović, Владимир Васильевич Лукин · IEEE Signal Processing Letters · 2005
Modification of the robust discrete Fourier transform (DFT) is proposed in order to achieve a high breakdown point for signals corrupted by complex-valued impulse noise with independent real and imaginary parts. Obtained results are compared with existing robust DFT forms. In addition, an adaptive procedure for selection of the modified robust DFT form is developed.
