Broadband Analog Self-Interference Cancellation Using Nonlinearity of Optical IQ Modulator for In-Band Full-Duplex Radios
We propose an optical IQ modulator-based nonlinear analog self-interference cancellation which can mitigate performance degradation caused by nonlinearity of the analog circuit. We achieved 29 dB cancellation with enhance signal-of-interest recovery performance in proof-of-concept experiment.
