OFDM is a technique used for bandwidth efficient communication over the channel. It provides excellent possibilities to adapt to the frequency-selectivity of the channel. The influence of impulsive noise in OFDM transmission is not well analyzed yet. In this paper, an algorithm for mitigating impulsive interference in OFDM based systems is presented which provides an iterative way suited to suppress impulse interference. The algorithm does not require any prior knowledge about the impulsive interference but only marginal increase computational complexity is done as compared to the conventional blanking nonlinearity approach.
