Abstract (in Japanese) (See Japanese page) 
(in English) In-band full-duplex is expected to improve the spectrum efficiency, but it requires self-interference cancellation.
Using nonlinear self-interference canceller, the performance is maximized with nonlinear transmitter.
In this paper, we introduce a digital predistorter (DPD) to nonlinearize the transmitter, and optimize the parameters of the DPD by using the Nelder-Mead method.
The simulation results show that the residual self-interference is significantly reduced compared to the case without the optimized DPD.
