Impulsive noise error cancellation in Orthogonal frequency division multiplexing (OFDM) system plays crucial role to determine overall performance bit error rate (BER). An algorithm of impulsive noise error cancellation, particularly for small size OFDM, was introduced by Jack K. Wolf in 1983. This algorithm determines parallelism between OFDM and Reed Solomon Code. Employing two zeros as redundancy in consecutive way in the transmitted data, the algorithm is capable to correct one additive impulsive noise error in the channel. Nevertheless, the estimation of amplitude impulsive noise is still poor. This caused by Gaussian amplification factor in the estimation amplitude of impulsive noise technique introduced by Jack K. Wolf. By removing this amplification factor the paper showing a better result in BER.
