Abstract

This paper proposes an adaptive bandwidth control method in a transmitter for multi-band OFDM transmission with spectrum sharing. The proposed method controls the bandwidth used by a multi-band system to reduce out-of-band distortion noise which interferes to other spectrum sharing systems. In addition, the method uses clipping followed by in-band and out-of-band filtering to satisfy required interference power conditions on other system bands. The evaluation results by computer simulations show that adaptive band selection in the proposed bandwidth control can reduce out-of-band distortion noise power so that the required conditions can be satisfied in other spectrum sharing systems.
