| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In-band full-duplex is expected to improve spectrum efficiency and throughput but self-interference (SI) cancellation is necessary.Previously proposed non-linear SI cancellers undergo ``full training" by treating the analog/RF regions as a black box.Therefore, when there are time-variations (TVs) in the RF elements, the canceller cannot perform ``partial re-training" based only on the TVs and must undergo re-training based on the characteristics of the overall transceiver.In this study, we focus on the TVs of power amplifier and low noise amplifier, and we propose a partial re-training method which re-trains time-varying amplifiers separately.Compared to the ``full re-training" method, the proposed method has higher SI cancellation performance and reduces computational costs. | |
