Abstract

This paper proposes a non-linear distortion noise control method for secondary systems in spectrum sharing. The proposed method is based on conventional clipping and filtering methods, and adaptively shapes distortion noise power to improve reception quality of secondary users with transmission power control. In this paper, optimal clipping levels to control in-band distortion noise are investigated, and then the spectrum property and BER performance with the clipping levels are evaluated. The results confirm that the proposed method can control the distortion power effectively in shared bands and realize secondary systems with less degradation of reception quality when sharing spectrum with transmission power control.
