Photonic based RF self-interference cancellation for 5G mobile communication systems

A photonic approach for RF self-interference cancellation based on phase modulation wavelength selective filtering is proposed. This scheme is quite compact and simple and free of auto-bias drift control unit. This scheme provides a potential solution to RF cancellation and full-duplex transmission for 5G wireless communications. The proposed RF SIC method is applicable for the WiMax (IEEE 802.16) wireless service and other high frequency bands.
