Abstract

To solve the problem of transceiver interference in the in-band full duplex (IBFD) system, a photonic radio frequency interference cancellation system based on phase modulators is proposed. Two phase modulators are used in a Sagnac loop to realize the modulation of the received signal and the local reference interference signal. Proper polarization control in the optical domain can finally cancel the self-interference signal. Experimental results show that the proposed scheme can achieve a single frequency interference suppression of more than 45 dB and a broadband interference suppression of more than 25 dB. The dynamic range of the system can reach 99.4 dB·Hz^2/3.
