A non-linear distortion noise power control method for multi-band OFDM transmission

This paper proposes a non-linear distortion noise power control method which uses clipping and in-band and out-of-band filtering methods for multi-band OFDM transmission. The proposed method selects appropriate clipping levels and filtering methods according to transmission power and required noise power conditions on own and the other system bands in a transmitter. The evaluation results show that the proposed method can control in-band and out-of-band distortion noise power so that required noise power conditions can be satisfied in multi-band transmission systems.
