| 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. |
