N2 - Compared with the half-duplex (HD), co-time co-frequency full-duplex (CCFD) technology can effectively improve spectrum utilization. Self-interference (SI) is one of the major factors limiting full-duplex (FD) performance. In this letter, we build the same scattering environment as the field measurement campaign, and simulate the FDSI and the conventional base station-to-base station (B2B) channels using ray-tracing technology. We simulate all the multi-path components (MPCs) and observe the power delay profiles (PDPs), received power, and delay spreads (DS) by changing the angular gap between and the height of the transmitting (Tx) and the receiving (Rx) antennas. The parameters and profiles of the simulated SI channel are consistent with and thus verify the measurement results. To further compare the FD channels and the conventional base station-to-user equipment (B2U) channel, we also compare the measured and simulated SI channels with the 3GPP channel model. It is interesting to find out that the channel characteristics are quite similar in the same scenario.
