Abstract
We present an efficient algorithm for the impulse noise correction in the context of OFDM systems. This correction algorithm is based on the use of an appropriate pilot tones distribution in order to cancel the impulse additive noise. We prove the efficiency of the presented algorithm and we derive a necessary and (sufficient) condition that guarantees a maximal correction capacity. Simulation results are given to support our claims.
