摘要：RF self-interference cancellation for Full-Duplex communication with a microwave photonic technique is proposed and demonstrated experimentally. It is based on an integrated dual-parallel Mach-Zehnder modulator (DP-MZM), where the sub-MZMs (MZM1 and MZM2) are biased at the quadrature point and the minimum point, respectively. It avoids the optical interference at the combining Y branch waveguide. The self-interference cancellation performance for 2.4 GHz, the standard of wireless service of WiFi (IEEE 802.11), is investigated. The cancellation depth as high as 83 dB is obtained for single frequency signal. And for the signal with a bandwidth from 10 MHz to 100 MHz, the cancellation depth larger than 44 dB is completed.
