Abstract(in English) | For increasing spectral efficiency toward the 6th generation mobile communication system, full-duplex cellular (FDC) system, which applies in-band full-duplex (IBFD) to the cellular system and can double spectral efficiency ideally, has been attracting. To realize FDC system, it is important to suppress the self-interference (SI), which occurs when transmitted signal is received by own receiver at a base station. Although many SI cancellations have already been proposed, the SI cancellation that take into account the 5G signal configuration and low-density parity-check (LDPC) code used in 5G have not been studied yet. In this report, we propose a digital SI cancellation to realize FDC system using 5G-based orthogonal frequency division multiplexing (OFDM) signal configuration. The proposed scheme modifies the demodulation reference signal (DMRS) configuration of 5G system to estimate SI channel with high accuracy for SI cancellation. The effectiveness of the proposed scheme is shown by computer simulation. |
