| Abstract(in English) | To further improve spectral efficiency for current wireless communication systems, in our previous studies, we proposed a lazy learning (LL)-based digital cancellation approach to suppress self-interference (SI) sent from a base station itself and enabled in-band full-duplex (IBFD) transmissions based on computer simulation platform. The core idea for our proposal is introducing an offline phase for database generation and an online phase for data transmission. In general, the database is used to record SI information and helps to perform SI suppression in online data transmission. In the present study, to further verify the performance of the proposed LL-based cancellation approach, we implemented an IBFD system by employing an universal software radio peripheral (USRP)-based transmission platform. Besides the proposed digital cancellation, we further introduced SI cancellations by antenna isolation and analog circuit design. Experiment results indicated that the implemented USRP-based IBFD system offered significant SI cancellation performance, and thus can demodulate desired signal with an acceptable bit error rate level. |
