Abstract :
In this paper, a novel clipping noise mitigation algorithm for OFDM system with large clipping ratio is proposed. We notice that the situation that there is only one sample above the clipping level appears with a large probability and the clipping noise on each subcarrier can be estimated in this case. Simulation result shows that the proposed algorithm can mitigate the clipping noise effectively.
