A Novel Self-Interfere Cancellation Technique Based on Operating-Point-Optimized Optical IQ Modulator for Co-Frequency Co-Time Full Duplex Wireless Communication

We propose a novel self-interference-cancellation technique by using an optical IQ modulator and a training-based optimization method. 35 dB cancellation ratio and 11 dB modulation gain for 100 MHz OFDM signal are achieved experimentally.
