Abstract



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.
