Abstract :
The discrete Fourier transform (DFT) has been proposed as a suitable technique for data transmission over channels that introduce impulse noise. However, in the presence of band-limited additive white Gaussian noise (AWGN), the performance of DFT coding is degraded. This paper deals with techniques for single impulse correction and combating the detrimental effect of band-limited AWGN
