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.
